Concurrent Dual-Band Receiver Based on Novel Six-Port Correlator for Wireless Applications
A concurrent dual-band six-port receiver based on real-valued time-delay neural network (RVTDNN) is proposed in this paper to retrieve two baseband signals from a dual-band radio frequency signal, concurrently. Different from the traditional six-port correlator, the new passive circuit correlator, w...

| description | A concurrent dual-band six-port receiver based on real-valued time-delay neural network (RVTDNN) is proposed in this paper to retrieve two baseband signals from a dual-band radio frequency signal, concurrently. Different from the traditional six-port correlator, the new passive circuit correlator, which is composed of one power divider and three quadrature couplers, has three inputs and three outputs, resulting in the decreased hardware complexity as well as circuit size, and a reduced power consumption for the system. The new six-port correlator, its output power as well as the baseband signal recovery theory are described and analyzed in detail. The calibration algorithm based on the RVTDNN is adopted to verify the feasibility of the concurrent dual-band receiver based on the proposed correlator circuit. Finally, a practical wideband six-port receiver test bench, which operates from 2 to 3 GHz, is built and tested using the common modulated signals. The calculated error vector magnitudes are all less than 2% verifying the correctness of this novel system implementation approach. |
