...h IBFD, one has to overcome the challenge of decoding in presence of co-channel interference or jointly decoding multiple users. There is a large body of literature on multiuser detection (see, e.g., [137], [138] and references therein). Compressed sensing has proven to be a useful technique for multiuser decoding in certain applications [60], [61]. Whether multiple transmissions can and should be sync...
