Abstract
The invention provides methods and apparatus for multiple user detection (MUD) processing that have application, for example, in improving the capacity CDMA and other wireless base stations. One aspect of the invention provides a digital signal processor ('DSP') that processes user waveforms. The DSP has an associated memory and an associated direct memory access ('DMA') controller that controls access to that memory. A programmable logic device (“PLD”) is coupled to the DMA controller and configures it to move data relating to user waveform characteristics from the memory to a buffer external to the DSP.
