Performance Analysis of Space–Time Line Code Systems with Phase-Shift Keying Modulation

The performance of space–time line code (STLC) systems employing phase-shift keying (PSK) modulation has not been studied, despite the distinct advantage of eliminating the need to estimate partial channel state information at the receiver. In this study, we comprehensively analyze the fundamental performance of STLC systems when utilizing PSK modulation, focusing on three essential aspects: 1) symbol error rate, 2) bit error rate, and 3) diversity gain and coding gain. The mathematical analysis is rigorously validated through numerical simulations, revealing system performance behavior concerning modulation order and the number of transmit antennas.
