Abstract
The work presents the impact of analog front-end effects on the BER performance of MIMO/SDMA-OFDM downlink transmission using minimum mean-squared error transmit processing at the access point. The implementation loss due to gain and phase mismatch, analog filtering, clipping and quantization, phase noise, and I/Q mismatch in the front-ends is given.
