Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A transmitter for transmitting a signal to a receiver in a wireless communication system, the transmitter comprising circuitry configured to:
modulate 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 modulate 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
transmit the FSK and ASK modulated signal.
