摘要:
The invention relates to a radio communication system in which a time slot of a frame of a multiframe signal allocated to the frequency control channel is modulated using an 8PSK modulation scheme to contain a tone having a frequency which GMSK modulation is unsuited to generate. This enables COMPACT-format signals to be distinguished from GSM - format signals and ensures backwards compatibility with all existing GSM mobile stations.
