dc.description.abstractAn efficient architecture for OFDM baseband receiver based on coordinate rotation digital computer (CORDIC) algorithm is proposed with channel state information (CSI). Two dual-mode CORDIC modules are designed for synchronization and equalization. A modified demapping method using CSI helps to provide sub-channel status, and therefore decreases packet error rates especially for some sub-channels with extremely low SNR. A combined algorithm suitable for CORDIC is proposed for not only estimate and compensation of channels but synchronization for carrier frequency offset and sampling. clock offset. Allocation, timing analysis and complexity for all functional blocks in the receiver are proposed, including front-end processing, FFT inner receiver, and outer receiver. Complete tests for packet error rate are simulated under an integrated platform considering of RF front-end non-ideal parameters, filters, quantization, and channel models. Simulation results Of practical circuits on AWGN and channel models are presented and prove the improvement of the receiver. The design occupies about 424k equivalent gate count and 7.3 mm(2) core size in 0.18 mu m CMOS.en_US
