Design of a krill herd algorithm based adaptive channel equalizer

This paper presents the design of an adaptive channel equalizer which is based on the recently proposed krill herd (KH) algorithm. The channel equalization problem, which is conventionally solved using gradient descent approaches, has been formulated as an evolutionary computing (EC) algorithm based optimization task. The performance of the proposed scheme has been compared with that obtained using other EC based equalizers and the KH algorithm based equalizer has been shown to offer improved channel equalization over the other schemes.
