Abstract

Non-coherent detection is usually applied in frequency hopping (FH) systems, because reliable coherent detection is very difficult. With multiple symbol differential detection (MSDD) a non-coherent system can achieve the performance of coherent differentially encoded systems. Due to its is complexity, two computationally simpler hard-decision feedback algorithms, multiple-symbol based decision-feedback differential detection (MSD DF-DD) and multiple symbol observation interval (MSOI) are studied and compared in partial-band jammed FH system. Additionally the system which usesmaximum-a-posteriori (MAP) algorithm as inner decoder is studied and its performance is compared to MSD DF-DD and MSOI. The performance improvement of the MSD DF-DD and MSOI using two simple limiters are also studied. The non-iterative versions of MSD DF-DD and MSOI have very similar performance. MSD DF-DD benefits from the iterative processing more effectively than MSOI in jammed and non-jammed simulations. The impact of jamming depends strongly on its bandwidth. The narrower the jamming band is, the more the performance of the algorithms decrease. MAP-based decoding performs significantly better than either of the algorithms.
