摘要：
Two MFSK modulation methods with time-frequency guards, using an LLR-based List Polar Decoder, are investigated for application to the underwater acoustic channel. Based on a number of published channel delay spreads, a 32FSK and a 32 subband 4FSK are chosen, having 185- and 1080 [bit/s], which are simulated in an AWGN channel, and tested at two sites in the Stockholm archipelago. The Polar Code is shown to have good performance in terms of BER and BLER, for both long and short frame lengths.
