A weighted interleaving system (10) is used for correlated channel coding. The weighted interleaving system (10) includes a weighted interleaver (12) having a pseudo-random demultiplexer (18), a first branch (28), a second branch (30), a third branch (32) and a pseudo-random multiplexer (38). The pseudo-random demultiplexer (18) receives input data bits at an input (20) and randomly distributes the input data bits to first (22), second (24) and third (26) outputs of the pseudo-random demultiplexer (18). The first branch (28) in communication with the first output (22) delays the transmission of the input data bits routed to it by a minimum delay. The second branch (30) in communication with the second output (24) delays the transmission of the input data bits routed to it by a delay uniform in probability from the minimum delay to a maximum delay. The third branch (34) in communication with the third output (26) delays the transmission of the input data bits routed to it by the maximum delay. The pseudo-random multiplexer (38) combines the input data bits received in its first (40), second (42) and third (44) inputs and routes the input data bits to an output (46).
A method for interleaving a plurality of input data bits with a weighted interleaver matched to correlation statistics of a channel, said method comprising the steps of:
