ABSTRACT:
An adaptive data rate communications system makes a compound error communications channel, with random and non-random impulsive noise, appear to be a gaussian channel. The process uses a cascade of digital error control coding, spread spectrum modulation, pseudo random chip interleaving, and feedback techniques. The communications process yields a dynamic chip to bit ratio for each frame. These communications process techniques along with the careful employment of the time/distance factors of distance between transmitter and receiver chip transmission rate, nominal chip to bit ratio, and number of bits in the frame yield a high throughput efficiency.
