Analysis of Frequency Domain Oversampled MMSE SC-FDE

Frequency domain oversampling (FDO) is investigated to improve the error performance of MMSE SC-FDE for multipath channels. The impact of FDO is analyzed in regard to the outage probability. The results show that FDO can significantly enhance the performance of MMSE SC-FDE when the ratio of block length to channel memory length is small such as in underwater acoustic channels. Its advantage is observed for moderate block length to channel memory length ratio for larger constellation sizes.
