System and method of transmitting and receiving satellite digital radio signals over an ODD number of frequency slots

摘要

A system (10) and method (200,300) for transmitting and receiving data which includes at least one satellite (14), at least one transmitter (12) in communication with the at least one satellite (14), and at least one receiver (16) in communication with the at least one satellite (14). The transmitter (12) modulates source data (18) into a first modulated signal using a first modulation and a second modulated signal using a second modulation, and transmits the first and second modulated signals over an odd number of frequency slots to the satellite (14). The receiver (16) receives the first and second modulated signals and demodulates at least one of the first and second modulated signals.
