Technology Brief:

Researchers at New Jersey Institute of Technology in the Department of Electrical and Computer Engineering have proposed a novel solution to optimize the compression strategies at the remote radio heads for maximizing sum rate performance.

 

Cloud radio access networks provide a promising approach to solve “bandwidth crunch” problem and to minimize the cost required for initial deployment or management of access points. On the uplink of the cloud radio access network, the base stations (BSs) operate as soft relay by compressing and forwarding the received signals to a cloud decoder. In the convention solution, the central decoder first decompresses the signals compressed by the BSs, and then decodes the mobile stations’ (MSs) signals. The invention is a novel design of cloud decoder and an optimization algorithm of compression, where by the cloud decoder performs joint decompression and decoding for maximizing sum-rate performance.  Further, numerical results have obtained which demonstrate the advantage of the invention compared to the conventional approach based on separate decompression and decoding.

 

Applications       

•       Cellular Services

•       Cellular Infrastructure

 

Advantages       

•       Significantly increase the sum-rate performance.
