In this paper an implementation of iterative joint detection for multiple access interference using direct-sequence code-division multiple-access (DS-CDMA) is presented. Results for multiple field programmable gate array (FPGA) platforms and multiple technology nodes for synthesized application specific integrated circuits (ASIC) are presented. The joint detection is performed using a generalized version of interleave-division multiple-access (IDMA) known as partition spreading (PS) CDMA. Decoding is performed using iterative methods from turbo and sum-product decoding. The synthesized ASIC system demonstrates a maximum aggregate throughput of 197 Mb/s for a fully loaded 50-user system, while the implemented FPGA 50-user system has a maximum aggregate throughput of 119 Mb/s. Index Terms-Digital circuits, direct-sequence code-division multiple access, field programmable gate arrays, interference cancellation.
