RECEIVER FOR THE GEO SATELLITE REVERSE LINK USING TAIL-BITING CODE

摘要

A receiver for the GEO satellite reverse link, which uses the tail-biting convolutional code for error control, and methods to solve the problem of channel estimation is described. The channel estimate is initialized at each state using the pilot channel. Branch metric computation is used for circular decoding of the tail-biting convolutional code. The technique is effective when partial tail-biting is implemented.
