An algorithm based on expectation propagation (EP) is proposed for noncoherent symbol detection in large-scale SIMO systems. It is verified through simulation that in terms of symbol error rate (SER), the proposed detector outperforms the pilotbased coherent MMSE detector for blocks as small as two symbols. This makes the proposed detector suitable for fast fading channels with very short coherence...
The growing demand for wireless services has led to the introduction of new paradigms in spectrum sharing such as the unlicensed ISMand U-NII bands and dynamic or opportunistic spectrum access through cognitive radios. Coexistence of users in these technologies leads to increases in co-channel interference (CCI) which needs to be appropriately mitigated. CCI is often modeled as a white Gaussian noise...
