个人简介编辑本段回目录

After 27 years, I “retired” from Bolt Beranek and Newman Inc. (BBN) in 1995. I had joined BBN in 1967 after three years at MIT Lincoln Laboratory and, except for a year in 1970-71, spent the rest of my business career with BBN, first as a computer programmer, then as a technical manager, and then as a general manager. At BBN, I had the good fortune to be involved in the beginnings of the Internet.
Over the next four years, after my retirement from BBN, I spent a little time with the Center for Quality of Management (CQM) and a little time with the Leaders for Manufacturing Program at MIT. The CQM web site included a photo of what I looked like as of a few years ago and other information relating to my participation in the CQM.

In 1998 I was pleased to be named to the hall of fame of my undergraduate college, San Francisco State, for having been involved in the early days of the Internet. My friend and classmate Stan Mazor — who was co-inventor of the micro-computer — went into my college hall of fame at the same time. This is among Stan’s lesser honors and my only honor. (I love being on the same list as Annette Benning and Danny Glover, among others — see full SFSU Hall of Fame list; I'm also listed with other notable alumni (under category 2 -- Science and Technology); and I was mentioned in SFSU Magazine, Vol. 1, No. 2, Spring 2001.)

More information about the early era of the Internet when I was involved can be found in the following books:

Where Wizards Stay Up Late by Katie Haffner and Matthew Lyon
Nerds 2.0.1 by Stephen Segaller which was the companion volume to the PBS TV show of the same name
Casting the Net by Peter Salus
Rescuing Prometheus by Thomas Hughes.
A Brief History of the Future: the origins of the Internet by John Naughton
Transforming Computer Technology: Information Processing for the Pentagon, 1962-1986 by Arthur L. Norberg and Judy E. O'Neill with contributions by Kerry J. Freedman, particularly chapter 4
The Dream Machine by M. Mitchell Waldrop, chapter 7.
In August 1999, the IEEE announced that BBN Technologies had been awarded a IEEE Corporate Innovation Recognition: “For pioneering contributions to computer networking technology through the development of the first packet switches, the ARPANET Interface Message Processor (IMP) and Terminal Interface Message Processor (TIP).” This work was done by a team of engineers and scientists which I had the great fortune to be part of. (Click here for a copy of the widely published photo of the BBN team I was part of, and click here for a more close up view of the IMP and team leader Frank Heart.)
In 2001, the Boston History and Innovation Collaborative honored BBN (and our ARPANET team) and did it again in 2007: click here for more info

My book Four Practical Revolutions in Management has been included on the Nippon Foundations's list of 100 Books for Understanding Contemporary Japan.

[Note: Much of the information in the conventional and business press about my career since my time as a programmer on the BBN ARPANET team is inaccurate; anyone including something on me in a piece you are writing might query me directly rather than trusting what has been written in the past.]

Technical writing
I have also written many technical papers, primarily related to my involvement in computer networking. As time permits or I find them already on the WWW, I'll post them to this web site or link to them. More recently I have been doing a lot of writing on the TeX typesetting system.
The ARPANET Design Decisions, by John McQuillan and me, Computer Networks, Vol. 1, No. 5, August 1977.
RFC 62: A system for interprocess communication in a resource sharing computer network
RFC 65: Comments on Host/Host Protocol Document #1
"RFC 333: Proposed Experiment with a Message Switching Protocol" (with R.D. Bressler and D. Murphy)
RFC 435: Telnet Issues (with Bernie Cosell)
RFC 636: TIP/TENEX Reliability Improvements (with J.D. Burchfiel, B. Cosell, and R.S. Tomlinson)
USER'S GUIDE TO THE TERMINAL IMP
My presentation on the ARPANET to the 1972 AFCET conference in Paris
Technical writing on my "travels in TeX land"
Over the past several years I have published a number of pieces on my on-going experiences while learning and using the TeX typesetting system.
    I have given this its own web page:
Travels in TeX Land
That page also has links to other TeX-related activities of mine, including an interview series (including an interview of me conducted by Karl Berry).
CV
A fairly complete list of my published technical (and management) writings is included in my CV

After three years at BBN, I spent a year in Norway developing the network described in the following paper: Remembering the LFK Network by Nils Liaaen and me in the Anecdotes section (pages 79-81) of the July-September 2002 issue (Vol. 24 No. 3) of the IEEE Annals of the History of Computing. Unfortunately, the copy at the Annals of Computing web site is accessible without charge only to people who have an appropriate IEEE membership (but check the For family, friends, etc., category further down this page). A preprint of the note by Nils and me is available here.

Some other activities of mine
Over my life I have moved serially through a number of hobbies, each one intense for a time, for example, contract bridge, amateur theater, postal chess, juggling, sail boating, and celtic traditional music. I’ve never gotten super good at any of these, but I’ve had a good time. Click here for photos relating to the last three of the above list.
Following are links relating to (a) about my only current heavy-duty recreation, movie going, and (b) what seems to be my current avocation, writing and self-publishing:

Movie going (brief notes on the last 1,000 movies I've seen)

Notes on self-publishing: based on my 2006 experience of publishing Breakthrough Management
A 2009 project to publish a book of interviews: the project is described in a video presentation and in a paper
And, based on the 2009 publishing project, new summary of my self-publishing insight: described in a video presentation and in a paper

线性预测编码的早期历史编辑本段回目录

根据斯坦福大学 Robert M. Gray 的说法,线性预测编码起源于 1966 年,当时 NTT 的 S. Saito 和 F. Itakura 描述了一种自动音素识别的方法,这种方法第一次使用了针对语音编码的最大似然估计实现。1967 年,John Burg 略述了最大熵的实现方法。1969 年 Itakura 与 Saito 提出了部分相关(en:partial correlation)的概念, May Glen Culler 提议进行实时语音压缩,B. S. Atal 在美国声学协会年会上展示了一个 LPC 语音编码器。1971 年 Philco-Ford 展示了使用 16 位 LPC 硬件的实时 LPC 并且卖出了四个。

1972 年 ARPA 的 Bob Kahn 与 Jim Forgie (en:Lincoln Laboratory, LL) 以及 Dave Walden (BBN Technologies) 开始了语音信息包的第一次开发,这最终带来了 Voice over IP 技术。根据 Lincoln Laboratory 的非正式历史资料记载,1973 年 Ed Hofstetter 实现了第一个 2400 位/秒 的实时 LPC。1974 年,第一个双向实时 LPC 语音包通信在 Culler-Harrison 与 Lincoln Laboratories 之间通过 ARPANET 以 3500 位/秒 的速度实现。1976 年,第一次 LPC 会议通过 ARPANET 使用 Network Voice Protocol 在Culler-Harrison、ISI、SRI 与 LL 之间以 3500 位/秒 的速度实现。最后在 1978 年,BBN 的 Vishwanath et al. 开发了第一个变速 LPC 算法。
