Abstract

A multiple-modulation communication system includes a transmitter (201, 203, 205, 207, 209, 211, 213, 215, 217, 219) that modulates and transmits communication signals modulated by a first modulation technique (201, 203, 205, 207) and communication signals modulated by a second modulation technique (211, 213, 215, 217). The first modulation technique and the second modulation technique are different. The communication system also includes a receiver (221, 223, 225, 227, 229, 231) capable or receiving the communication signals modulated by the first modulated technique and the communication signals modulated by the second modulation technique and demodulating the communication signals.
