document: A fast implementation of correlation of long data sequences for coherent receivers Coherent reception depends upon matching of phase between the transmitted and received signal . Fast convolution techniques based on fast Fourier transform -LRB- FFT -RRB- are widely used for extracting time delay information from such matching . The latency in processing a large data window of the received signal is a serious overhead for mission critical real time applications . The implementation of a parallel algorithm for correlation of long data sequences in multiprocessor environment is demonstrated here . The algorithm does processing while acquiring the received signal and reduces the computation overhead considerably because of inherent parallelism
