Error rates calculation and performance analysis of (2,1) STBC systems

In this paper, closed-form solutions for error rates of MPSK modulated (2,1) STBC systems are derived. With the hypothesis of ideal channel estimation, a general method of formulating the (2,1) STBC MPSK systems´ error rates is explicated and the closed-form solutions for symbol error rate and bit error rate are put forward, which provides the designers with a more accurate standard for evaluating STBC system´s performance than the Chernoff bound. Computer simulations demonstrate the consistency between practical error rates and theoretical results.
