Abstract

A modem structure for high speed digital (QPSK) communications in the time division multiple access (TDMA) mode is presented that overcomes the problems of intersymbol interference and acquisition of each TDMA burst. The first part of the design involves the examination of an IF adaptive equalizer to compensate for channel distortion. The second part of the design involves a reexamination of traditional carrier and clock recovery networks and the proposal for their replacement by (560 MHz) synchronous oscillators
