Abstract: This paper investigates detector architectures for wireless handsets employing DS-CDMA. The code-matched filter (MF) and minimum output energy (MOE) detectors are analyzed with respect to fixed-point arithmetic behavior. Architectures employing fixed-point arithmetic are then proposed for these detectors. The maximum throughput of these architectures and the associated costs in terms of area usage and power consumption are evaluated. Results of the fixed-point analysis indicate that the MOE detector is more susceptible to quantization than the MF detector. Results of implementation indicate that the superior performance of the MOE detector is achieved at a considerably higher cost in terms of area usage and power consumption. Finally, comparison of hardware implementation with software-based DSP implementation indicates that software approaches result in considerably lower throughputs.
