<p>A system and method for transmission and receipt of multi-band communication according to their time slot sequence includes at a transmitting end: an encoder for encoding data according to a time slot position (s1, s2, s3,s4) for each frequency band; an RF modulator for modulating encoded data over a predetermined plurality of frequency bands (f4, f3, f2, f1) selected from a plurality of frequency bands (f1, fn). The predetermined plurality of frequency bands are independent of each other and an order of transmission of the predetermined plurality of frequency bands being irrelevant, unlike the dependency in spectral keying. The present invention frees up the order of the frequency bands being transmitted, so that they can be used for channelization, security or other purposes and requires less complicated circuitry at the receiver end.</p> |
