| Abstract: | To analyze the impact of inter-carrier interference (ICI) caused by pulse blanking on the error performance of the space-time block coding-orthogonal frequency division multiplexing (STBC-OFDM) receiver, the analytical expression of the signal-to-noise ratio (SNR) for the STBC OFDM receiver with pulse blanking is derived over the frequency selective Rayleigh fading channel, and the effect of pulse blanking on the symbol error ratio (SER) for the STBC-OFDM receiver is also analyzed quantitatively based on the SER expression. Simulation results validate the accuracy of derived formulas. |
