Abstract

Wireless receiver and method of operating a wireless receiver in a wireless communication network for: receiving a signal, the received signal comprising data containing at least one symbol from a symbol alphabet, the symbol alphabet consisting of complex values that define a direction in the complex plane, the received signal further comprising interference; measuring the variance of a first component of the received signal that is perpendicular to the defined direction in the complex plane; estimating the interference power of the received signal using the measured variance of the first component of the received signal; estimating a total power of the received signal; estimating the power of the at least one symbol of the received signal by subtracting the estimated interference power from the estimated total power of the received signal; and based on the estimated interference power and the estimated power of the at least one symbol of the received signal, performing at least one of the steps of: processing the received signal, and generating control information related to the transmission of a further signal from the wireless receiver.
