Abstract:
1. A communication system for sending and receiving data, said system comprising: a transmitter and a receiver wherein a general binary coded Orthogonal Frequency-Division Multiplexing carrier scheme is provided between said transmitter and said receiver to thereby increase code density and data rate per Hz of bandwidth; a plurality of narrow band carrier frequencies, wherein, said narrow band frequencies are orthogonal and are transmitted in a binary code to represent data; and wherein, said narrow band carrier frequencies includes narrow band separation between orthogonal carriers of the order of 0.1 MHz and providing a bandwidth of the order of 3.2 MHz for 32 carriers thereby allowing said bandwidth to transmit at least 6 Mbps in a 2 of 32 Orthogonal Frequency-Division Multiplexing.
