Title
A novel joint estimation and compensation algorithm for non-idealities of analog front-end in DC-OFDM system
Abstract
To solve the problem of deterioration of system performance for the analog front-end (AFE) non-idealities, such as Carrier Frequency Offset (CFO), IQ mismatch and Sampling Frequency Offset (SFO) in OFDM system, this paper proposes a novel joint estimation and compensation algorithm, which estimates and compensates CFO and IQ imbalance in time domain, while compensates Residual Carrier Frequency Offset (RCFO) and SFO in frequency domain. Compared with the traditional algorithms, the proposed scheme uses fewer data supporting resources to improve the estimation accuracy by introducing an iterative updating scheme. Significant non-idealities introduced, the proposed scheme is also able to achieve a low bit error rate.
