Packet Radio Communications

Abstract

Three major areas of activities in support of packet radio communications are reported in »Sis document. These are: (1) Analysis of the pseudorandom code spread spectrum technique, (2) evaluation and selection of the pseudorandom codes for the experimental repeater, and (3) development of a signal capture model The analysis of the code spread spectrum includes considerations of synchronization and multiple access capabilities. The code selection is based on the computer-derived side lobe properties and crosscorrelation of high data rate codes with low data rate codes. The developed capture model is based on the repeater design currently being developed and will be used to model capture in the existing packet radio network simulation models, which preseitly have no capture Also, a brief status report of the repeater equipment development is included in the introduction.■

Technology in the Art of Recording

“…Technological innovation in the recording studio has been consistent with the argument that the introduction of new technology is invariably for the purposes of increasing control over the workforce. 15 The workforce in recording has never been large, and so controlling it has not been perceived as a major problem but may nevertheless be thought desirable.…”
