| Abstract: |
We describe the implementation of a low-complexity minimum mean-square error (MMSE) turbo-equalizer on Texas Instruments (TI)TMS320VC5509 device, a low-cost 16-bits fixed-point DSP typically designed for mobile terminals. A data rate of 207 Kb/s per iteration has been achieved. With carefully optimized data quantization, the resulting fixed-point receiver exhibits virtually no performance degradation with respect to an ideal (unquantized) floating-point turbo-equalizer. |
