Abstract:
1. A method comprising: determining a received signal includes phase noise comprising at least a common phase error component and an inter-carrier-interference component; causing, at least in part, the common phase error to be corrected based, at least in part, on one or more pilot carriers; causing, at least in part, an estimate of a main signal component to be subtracted from the one or more pilot carriers; determining a sequence of estimated coefficients of a multiplicative phase noise sequence, wherein the determination of the sequence of estimated coefficients comprises processing an estimated value of a first coefficient of the sequence of estimated coefficients to produce a result based on the first coefficient and subtracting the result when estimating a next coefficient of the sequence of estimated coefficients to hone in on an estimated value of the next coefficient; causing, at least in part, the inter-carrier-inference to be corrected by processing the multiplicative phase noise sequence using the sequence of estimated coefficients; and causing, at least in part, an equalized data signal to be output based, at least in part, on the corrected common phase error and the corrected inter-carrier-interference.
