BUILT-IN-SELF CALIBRATION FOR I/Q IMBALANCE IN QUADRATURE MODULATOR.
Recent technologies of digital and analog signal processing applications have a lot of interference occurring due to signal transmission traffic in air medium. As such, transmission and reception of RF signal tend to have interference, calibration imbalance and jitter noise. In this digital modulati...

As such, transmission and reception of RF signal tend to have interference, calibration imbalance and jitter noise. In this digital modulation and demodulation technique of Quadrature transmission we will have I/Q based differential signal method to reduce this calibration imbalance. However some errors will still occur in gain and phase mismatches on high frequency range transmission. The proposed work will designed a Quadrature amplitude modulation in phase shift keying method of QAM-QPSK modulation and demodulation in 4, 8, 16 quadrant in differential signal processing using the technique of digital frequency calibration with carrier signal generation. This method is fully designed with digital quadrature method in FPGA using VHDL. The output will be measured in the extraction, calibration of gain and phase mismatch and also verified in the compared terms of bit error rate, area, delay and power using Xilinx FPGA S6LX9-2FG144. pubtype: Academic Journal doctype: equations & formulas pictorial tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
