Efficient Feedback Design for MIMO SC-FDMA Systems
An efficient feedback design for single carrier frequency division multiple access (SC-FDMA) multiple input multiple output (MIMO) communication systems is described. We consider a codebook-based approach for quantization of feedback information. Differential transform processing is used for feedback design to reduce feedback overhead. Jacobi rotation is utilized for generating the MIMO pre-coding matrix and feedback information. Differential processing is used to generate the updates iteratively for the feedback information between feedback intervals. An approach of combined differential and non-differential feedback is considered for reduced feedback overhead and improved performance. A differential feedback with periodic error reset for differential processing is described. The performance of MIMO communication systems using pre-coding/transmit beamforming and the described feedback design is evaluated for SC-FDMA systems. The effects of pre-coding and feedback quantization, sub-ca...
