WiBench
WiBench is an open-source configurable wireless benchmark suite that includes the key signal processing kernels of the baseband system in many mainstream wireless protocols, include 802.11, WCDMA and LTE. It was designed by me and Yajing Chen at University of Michigan, Ann Arbor.
WiBench kernels are self-contained configurable blocks that can be tuned to meet the different system requirements. Several standard channel models are also included to study system performance, such as the bit error rate. The suite also contains an LTE uplink system as a representative example of a wireless system that can be built using these kernels. WiBench is provided in C++ to make it easier for computer architects to profile and analyze the system. A MATLAB version is also included for debugging purposes.
The download of WiBench is available through this link. More detailed information can be found on the WiBench website.
