On transmission performance of OFDM-based schemes using MMSE-FDE in a frequency-selective fading channel

There has been greatly increasing interest in orthogonal frequency division multiplexing (OFDM) for broadband wireless transmission due to its robustness against multipath fading. However, OFDM signals have high peak-toaverage power ratio (PAPR), and thus, a power amplifier must be operated with a large input power backoff (IBO). Recently, OFDM combined… CONTINUE READING
