ABSTRACT:
A Coded Data Multiple Access (CDMA) communication system in which a bit stream of digitized data is convolutionally encoded, and interleaved, to provide time diversity for consecutive output bits of the encoder. The interleaved encoded message is packetized into blocks to which synchronization and user identity preambles are provided. Each packet is transmitted in time compressed bursts at random time intervals.
