Abstract: A method and apparatus for signal detection and error detection in a multi-band system, the method for error detection comprising the steps: receiving a plurality of bursts, each burst occupying at least one of a plurality of frequency bands, the plurality of bursts encoding a symbol, the symbol corresponding to data, wherein the symbol is encoded such that a burst occupying each frequency band is transmitted a specified number of times within the plurality of bursts; determining that a given burst has not been detected the specified number of times; and declaring a transmission error for the symbol. In one variation, the frequency bands comprise wideband frequency bands.

Abstract: A method of data transmission according to one embodiment of the invention includes encoding a set of data values to produce a corresponding series of ordered n-tuples. The method also includes transmitting, according to the series of ordered n-tuples, a plurality of bursts over a plurality n of frequency bands. Specifically, for each of the plurality of bursts, a frequency band occupied by the burst is indicated by the order within its n-tuple of an element corresponding to the burst. A bandwidth of at least one of the plurality of bursts is at least two percent of the center frequency of the burst. Information is encoded into an additional modulation, e.g., amplitude, width or polarization modulation, of at least one of the plurality of bursts.
