Vector Approximate Message Passing Based OFDM-IM Detection for Underwater Acoustic Communications

Vector Approximate Message Passing Based OFDM-IM Detection for Underwater Acoustic Communications

Orthogonal frequency division multiplexing with index modulation (OFDM-IM) has great potential for the implementation of high spectral-efficiency underwater acoustic (UWA) communications. However, general receivers consisting of the optimal maximum likelihood detection suffer from high computational...
