Abstract

Disclosed is an encoder, interleaver and splitter design approach for increasing system capacity. This is accomplished in a dual path embodiment by splitting the data stream into two subsets where one subset contains even number position bits of the original set and the other subset comprises the remaining odd bits. Each of the subsets may then be interleaved in standard fashion. This approach ensures that consecutively occurring bits in the original set are never transmitted from the same antenna and can be used to maximize the distance (and accordingly the time of transmission) between alternately occurring bits. The thought process behind this embodiment of the invention may be used to design a single interleaver as practiced in the prior art to accomplish the equivalent end result. The design process may be modified to include any number of transmission paths. Additional improvement of capacity may be obtained where each subset is interleaved in a manner to maximize the time separation between transmission of data bits, originally occurring L bits apart, prior to splitting or interleaving, in each of L data paths.
