TLDR
Computer simulations show that the performance of FSBLP is clearly superior to that of the other structures, and applications of PP for fading channel equalization and co-channel interference suppression in a 16-level quadrature amplitude modulation receiver system are considered.Abstract:
The paper investigates the behaviours of polynomial perceptrons (PP) introduces a fractionally spaced recursive polynomial perceptron (FSRPP) with low complexity and fast convergence rate. The nonlinear mapping abilities of PP and FSRPP are analyzed. Applications of PP for fading channel equalization and co-channel interference (CCI) suppression in a 16-level quadrature amplitude modulation receiver system are considered. Computer simulations are used to evaluate and compare the performance of PP and fractionally spaced bilinear perceptron (FSBLP) with that of the synchronous decision feedback multilayer perceptron (SDFMLP), fractionally spaced decision feedback multilayer perceptron (FSDFMLP), and the conventional decision feedback equalizer (DFE). The results show that the performance of FSBLP is clearly superior to that of the other structures.read more

Robust GMSK Demodulation Using Demodulator Diversity and BER Estimation
TL;DR: This research investigates robust demodulation of Gaussian Minimum Shift Keying (GMSK) signals, using demodulator diversity and real-time bit-error-rate (BER) estimation, and formally introduces the concept of demmodulator diversity, a new idea which consists of a bank of demodulators which simultaneously demodulate the same signal and take advantage of the redundancy in the similar signals.
