ADVANCED INTERFERENCE CANCELLATION FOR PRECODED GSM EDGE RADIO ACCESS NETWORK (GERAN)

摘要

An interference cancellation receiver for a pre-coded orthogonal frequency division multiplexed (OFDM ) based system combines temporal interference cancellation within the OFDM framework. Multi-path equalization and inter-symbol interference (ISI) cancellation are performed on a time domain channel estimate of a received signal. An output from the multi-path equalization is transformed to the frequency domain. Inter-channel interference (ICI) is performed in the frequency domain on an equalized signal from the multi-path equalization after transforming the equalized signal from the time domain to the frequency domain.
