Apparatus and method for receiving differential space-time block code

摘要

Provided is an apparatus and method for receiving a differential space-time block code (STBC) without estimating a channel characteristic using an additional training sequence in a wireless communication system using a plurality of transmission/reception antennas. The apparatus for receiving a differential STBC includes a detector for detecting a symbol from a received differential STBC using a trellis diagram and a Viterbi algorithm, a deinterleaver for deinterleaving the detected symbol, and a decoder for decoding a signal deinterleaved by the deinterleaver.
