TRANSMISSION METHOD AND RADIO SYSTEM

摘要

The invention relates to a data transmission method and a radio system implementing the method. A transmitter has at least two modulation methods by which it can modulate a signal. One or more demodulators (106) of the receiver demodulates the received signal in a manner which corresponds to each modulation method. An impulse response block (108) forms for the received signal an impulse response which corresponds to each modulation method used. The modulation method used for the signal is inferred in a reference block (110) from the impulse response estimate. The signal according to the inferred modulation method is detected in a detector (114).
