چکیده

In this paper, 1-bit, 2-bit and 3-bit feedback performances of Space Time Trellis Code in Rayleigh channel are studied. The open loop performance shows better result whereas due to complexity of trellis the performance degrades with feedback. But still with increasing the number of bits, the error rate performance improves again. In case of error rates, 3bit feedback system has the lowest value. 2-bit feedback system needs lowest time for simulation and 1-bit feedback offers highest channel capacity.

Concatenated space-time codes for quasi-static fading channels: constrained capacity and code design

Abstract— The problem of designing codes with close-tocapacity performance on the multiple-input multiple-output (MIMO) quasi-static fading channel (QSFC) is addressed. We consider three different coding schemes – namely, direct transmission of random-like codes, concatenation with linear processing orthogonal space-time block codes (o-STBC) and concatenation with space-time trellis codes (STTC...
