Abstract
In this paper, we investigate the analog front-end imperfection in multi-band orthogonal frequency division multiplexing (MB-OFDM) ultra-wideband (UWB) systems and propose a joint estimation and compensation scheme. The estimation of CFO and SFO is presented on frequency domain, which is robust to frequency dependent I/Q imbalance. After that, I/Q imbalance and channel response is jointly estimated with partial compensation to CFO and SFO. Finally, pilot sub-carriers within OFDM symbols are used to track the residual phase distortion. Simulation results show that the proposed joint estimation and compensation scheme achieves 0.3dB SNR advantage in practical MB-OFDM UWB systems comparing to traditional joint estimation algorithm.
