摘要 为获得衰落信道中空时网格码(STTC)的性能估计,对STTC的成对差错概率(PEP)进行了研究.利用矩母函数(MGF)分析方法,推导出对于Rician和Nakagami-m不同衰落信道条件下STTC的PEP的单变量积分形式的准确表达式,并且分别对快衰落和慢衰落信道下PEP的性能进行了分析.研究表明,利用PEP单变量积分形式能够更精确地估计STTC的性能. The pairwise error probability （PEP） of space-time trellis codes （STTC） was investigated to evaluate the performance of STTC over fading channels. Using the moment generating function （MGF）-based approach, the exact expressions for the PEP of STTC over Rician and Nakagami-m fading channels were derived in terms of the single variable integral form. The PEP performance over fast and slow fading channels were also analyzed, respectively. Results show that the expressions for the PEP can be used to evaluate the performance of STTC more accurately.
