  • Abstract
    VPSK modulation is a new and as yet little known modulation method that compresses the RF data transmission bandwidth 10/1 or 12.6/1. Unlike other compression methods such as QAM, VPSK does not suffer a loss of S/N with increasing compression. VPSK is BPSK modulation with the data encoded prior to transmission by Single Sideband FM-SC. This results in an Eb/η value that is theoretically better than that for QPSK, even though the occupied bandwidth is only 1/5 as large. Eb/n values of 14 dB for 10-6 BER are being obtained in the field at 10 bits/Hz compression. Due to this low Eb /η, VPSK is the only high compression method suitable for use on satellites
