Minimum Bit Error Rate Multiuser Detection in Multiple Antenna Aided OFDM
In this contribution, we propose a Minimum Bit Error Rate (MBER) multiuser detector for Space Division Multiple Access (SDMA) aided Orthogonal Frequency Division Multiplexing (OFDM) systems. It is shown that the MBER detector outperforms the Minimum Mean

Peak-to-average Power Ratio of Orthogonal Frequency Division Multiplexing
Orthogonal frequency division multiplexing (OFDM) is successfully used in many wireless digital communication systems over multipath channels. One of the principal disadvantages of OFDM is the occurrence of high peak to average power ratios (PAR). Many
