Modulated Coding for Digital Communication Systems Under ISI/Multipath Fading and Jamming

摘要

This report describes the main research achievements during the time period cited above on the research project in the area of telecommunications. The main achievements include the systematic study of modulated codes that are convolutional codes defined on real/complex field over intersymbol interference, multipath, jamming channels. We obtained the joint maximum-likelihood decoding, and the MMSE-DFE decoding algorithms. We proved the existence of the coding gain compared to the uncoded AWGN channel. We also obtained space-time modulated codes for multiple transmit and multiple receive antenna systems. A new precoded OFDM system was also obtained which is robust to spectral-nulls.
