| Popis: | The Digital beamforming, MIMO (Multiple InputMultiple output) communications, electronic warfare, RADAR are the potential applications that depends on multichannel phase coherency for the signal processing. This paper presents an elegant 4-channel internal monitoring calibration technique based on CORDIC algorithm that efficiently implements trigonometric function in FPGA hardware. The proposed method is implemented in space grade Virtex-5 FPGA. The hardware results show that the calibrated signal has a phase RMS accuracy of 0.2 degrees between the calibrated channels. |
