Symbol-by-Symbol Detection of Space-Time Coded Continuous Phase Modulated Signals

Paper i proceeding, 2005

We investigate the detection of space time codes (STC) modulated using continuous phase modulation (CPM) in quasi-static fading channels. An optimum symbol-by-symbol iterative detector is derived and its practical implementation using the concept of principal component analysis (PCA) is considered. To assess the performance, numerical examples for different STC-CPM schemes are presented. According to the simulation results, the proposed detector obtains very good power efficiencies. Moreover, the bit error rate (BER) performance of the proposed detector for quasi-static fading is very close to the case without fading, highlighting its effectiveness to mitigate fading.
