High Sampling Rate Spatially Distributed Direct-Conversion Receiver Operating at 5 GHz

This letter introduces a spatially distributed wireless interferometric receiver that leverages wave correlations for baseband symbol extraction. Various PSK and QAM modulation schemes operating at 5 GHz are implemented and tested alongside fast logarithmic power detectors. Experimental results demonstrate the receiver’s potential, achieving a data rate of 120 Mb/s with an 8.9% error vector magnitude (EVM) for QAM-64 modulation.
