High Immunity Triple Channelized Correlation Receiver

It is well known that multiple correlation of deterministic signals allow more information about those signals to be extracted. The triple correlation receiver is self acquiring in the sense that there is no need for local reference PN code. The received signal acts as its own reference. The paper describes the theory of triple correlation receiver using code of m-sequence of length 127. This proposed triple correlation receiver is testified by simulation using different delay pairs for different generating polynomials of different length. A technique to improve triple correlation receiver called channelized receiver is proposed. The channelized receiver has been shown and compared with triple correlation receiver. Analyses of the triple correlation receiver in AWGN are performed. The performance of the proposed receiver in additive white Gaussian noise is simulated. High immunity of the channelized receiver against noise is introduced and discussed.
