Abstract (en)

[origin: WO9955048A1] The invention relates to a method and arrangement for modulating a signal to be transmitted using M-level continuous phase modulation, wherein M can obtain values (2, 4, 8, ...) and the symbols to be transmitted comprise more than one bit, the arrangement comprising a coder (104) and a frequency modulator (120). In order to flexibly enable high data rate transmission in a narrow frequency band, the coder (104) is arranged to code each symbol to be transmitted into a separate binary sequence to yield an M-level PSK constellation.
