frequency offset cancellation using cp_ica technique
₹1250-2500 INR / ชั่วโมง
ICI causes severe degradation of the
BER performance of the OFDM receiver. In this paper, we
propose a new ICI cancellation algorithm which estimates
frequency offset at the time-domain by using the Cyclic Prefix
(CP) based Independent Component Analysis (ICA) method to
the received subcarriers. We derive the frequency offset
estimation technique by using CP-ICA analyzing the phase
rotation of the OFDM symbols. This algorithm is based on a
statistical blind estimation method, which mainly utilizes the
Eigenvalue Decomposition (EVD), rotating phasor and the 4th
cumulants. In the case of 0.0<ε <1.0, simulation results show
that the proposed frequency offset estimator is more accurate
than the other estimators under AWGN and Rayleigh flat fading
channels.
