Apparatus and method for receiving differential space-time block code

摘要

The present invention relates to a receiving apparatus and a method of differential space-time block codes, and more particularly, for a number of transmission / using a separate training sequence in a wireless communication system using a receiving antenna, to an apparatus and method for receiving a differential space-time block code encoding without estimating the channel characteristics. ; To this end, the present invention receiver of the differential space-time block code according to a, by using a trellis diagram and Viterbi algorithm from the differential space-time block code detector for detecting a received symbol, deinterleaving the detected symbols to a de-interleaver, and the de-interleaving and characterized in that a signal having a decoder for decoding, resulting in the present invention has the effect of receiving a differential STBC with performance similar to the conventional coherent detection scheme without channel estimation.
