摘要
A deterministic mismatch model called Sparsity Enhanced Mismatch Model-Reverse discrete prolate spheroidal sequence which leads to a two stage transceiver design that outperforms precoding only strategy incorporating norm ball mismatch modeling. The inherent sparsity in the channel is brought forth by modeling the channel using a basis expansion model where discrete prolate spheroidal sequence is used as a basis. The sparsity enhanced mismatch model reverse discrete prolate spheroidal sequence disclosed herein better accounts for the channel state information estimate mismatch compared to the norm ball mismatch. The Sparsity Enhanced Mismatch Model-Reverse based transceiver system, which includes a two-stage precoder and decoder, allows the transceiver to utilize higher transmit power without violating the interference constraint placed at the victims, resulting in enhanced performance in the communication link.
