Implementation of Tomlinson Harashima Recorder(THP) in Cloud Radio Access Networks (CRANs)

The evolution of cellular communication networks from 1G through 4G has resulted in a steady increase in the allowable rates for users (UEs). However, other cell interference (OCI) still remains the performance limiting factor. OCI is the interference from signals received from other cells. Mitigation of OCI using interference cancellation strategies results in improvement of allowable rates. This can be achieved by Cloud radio access networks (C-RANs), which is also labeled as network multiple-input-multiple-output (MIMO) centralized precoding architecture in literature.Precoders in CRANs are designed to presubtract the known interference at the transmitter. It basically exploits transmit diversity by weighting information stream, i.e. the transmitter send the coded information to the receiver in accordance with the pre-knowledge of the channel. A nonlinear precoder named THP precoder is implemented in my project work
