Luttrell S P and Pritchard J A S, July 1986, A compact digital communications system part 1: rapid carrier acquisition, RSRE technical report (Malvern, UK), 3925
The problem of reducing the carrier centre frequency ambiguity in low data rate satellite communications is well known. Prior solutions to this problem have been slow, bulky or expensive. Our proposed solution does not have these drawbacks, and it is easily implemented in readily available digital hardware. This is achieved by using a 1 bit digital emulation of a bank of forced LCR oscillators to achieve an approximate Fourier decomposition.
