I would like to do N, where N is larger than 4, correlators on the FPGA in order to do code acquisition for code division multiplexing. I would also like to do beam steering experiments on four channels. All involve multiplications and the lower the latency, the better. Then the question becomes

Just for grins here's a GNU/Radio plot of a local FM station transmitting HDRadio, with prominent digital sidebands: http://webpages.charter.net/cswiger/hdradio_fft.jpg Not sure what the spike at +90k is, SCA maybe. paper on it here: http://www.bdcast.com/HDRadio/papers/ "THE STRUCTURE AND GENE
