Performance analysis of QPSK system with Nakagami fading using efficient numerical approach

An efficient numerical method is developed to analyze the bit error rate of PSK Nakagami-m fading systems with imperfect carrier recovery. We evaluate the detection loss suffered due to the carrier recovery for different rms phase error values when coherent QPSK system are used in wireless channels. Our results are useful in the design of practical systems and will enable designers to determine the phase precision of PSK systems in wireless environments.
