Classification: CPC H | IPC H

Claim 0:
1. A method performed in a transmitter for transmitting a signal to a receiver in a wireless communication system, the method comprising:
modulating the signal with a first data stream at a first data rate using binary frequency shift keying (FSK) modulation to generate an FSK modulated signal, and further modulating the FSK modulated signal with a second data stream at a second data rate using binary amplitude shift keying (ASK) modulation to generate an FSK and ASK modulated signal, the ASK modulation including Manchester coding, and the first data rate being greater than the second data rate to enable demodulation of two frequencies of the FSK modulation at equal power; and
transmitting the FSK and ASK modulated signal.
