Abstract :
We present a new differential space-time block code (DSTBC). The scheme can be represented by a trellis and decoded using the Viterbi algorithm. It provides a differential coding gain of 1 dB due to redundancy introduced in the differential encoding and it is only 2 dB away from the corresponding coherent space-time block code (STBC).
