Abstract

A joint detection system and associated methods are provided. The joint detection system is configured to perform joint detection of received signals and includes a joint detector accelerator and a programmable digital signal processor (DSP). The joint detector accelerator is configured to perform front-end processing of first data inputted to the joint detector accelerator and output second data resulting from the front-end processing. The joint detector accelerator is further configured to perform back-end processing using at least third data inputted to the joint detector accelerator. The programmable DSP is coupled to the joint detector accelerator, and the programmable DSP is programmed to perform at least one intermediate processing operation using the second data outputted by the joint detector accelerator. The programmable DSP is further programmed to output the third data resulting from the intermediate processing operation to the joint detector accelerator.
