Abstract:
1. A method for operating a receiver system to perform blind equalization, the method comprising: receiving, by the receiver system, a communication signal from a communication channel in response to a transmission of a transmit signal onto the communication channel by a transmitter; generating, by the receiver system, samples of the received communication signal; equalizing, by the receiver system, a block of the samples, wherein said equalizing includes minimizing a function J of a vector argument f to determine a minimizing vector f updating, by the receiver system, the current modulus parameter value γ based on a ratio of a fourth moment value to a second moment value, wherein the fourth moment value is a fourth moment of the sequence {y repeating said equalizing and said updating a plurality of times using respective blocks of the samples; and convolving at least a subset of the samples with the minimizing vector f
