Abstract (en)
[origin: WO2008069556A1] An amplitude differential shift keying (A-DPSK) modulation apparatus and method, and an A-DPSK demodulation apparatus and method are provided. The A-DPSK modulation apparatus includes: a first modulation unit for DPSK (differential phase shift keying) -modulating a first data sequence; a second modulation unit for ASK (amplitude shift keying)-modulating a second data sequence and inserting pilot signals into the ASK-modulated signal; and a multiplier for multiplying outputs of the first and second modulation units and outputting the multiplication result.
