A novel frequency-domain IQ imbalance estimation and compensation algorithm
To solve the problem of deterioration of system performance for the RF front-end distortion and IQ imbalance in orthogonal frequency division multiplexing（OFDM）system，a novel IQ imbalance frequency domain estimation and compensation algorithm was proposed.The effect of channel could be offset，the co...

| description | To solve the problem of deterioration of system performance for the RF front-end distortion and IQ imbalance in orthogonal frequency division multiplexing（OFDM）system，a novel IQ imbalance frequency domain estimation and compensation algorithm was proposed.The effect of channel could be offset，the complexity of algorithm could be reduced and the implemention conld be achieved easily using two different pilot signals on one sub-carrier.The simulation results show that the algorithm not only greatly reduces the computational complexity，but also gets a better estimation and compensation performance，and the performance is better than traditional algorithms. |
