Abstract :
We analyze the performance of transmit beamforming on multiple-antenna Rayleigh fading channels with imperfect channel feedback. The feedback imperfections are characterized by noisy channel estimation, feedback delay, and finite rate channel quantization. We develop a general framework, valid for an arbitrary two-dimensional linear modulation, that captures the aforementioned imperfections, and derive the average symbol and bit error probability expressions for M- PSK constellation. We show that the proposed analytical formulation is valid for frequency-domain duplexing system with/without finite rate channel quantization and time-domain duplexing system. The simulation results show accurate agreement with the analytical expressions.
