Signal Code Constructions for Channels with Powerful Wideband Interference

In this paper, we consider data transmission in "bad" channels with low snr and wideband interference. We propose a code construction based on frequency shift keying with fast frequency hopping. We also propose two new decoders that are more robust in regard to interference compared to the known OSN decoder. The computer simulation has shown that the proposed decoders have higher error correction efficiency than the previously known decoder.
