Abstract

A system for wireless communication reduces implementation complexity for symbol level interference cancellation as applied to physical control and data channels, such as the physical downlink shared channel (PDSCH) and physical downlink control channel (PDCCH). A user equipment (UE) categorizes tones of a signal into tone groups. A different noise whitening matrix is applied to each tone group for demodulation and decoding of the signal.
