Abstract:
1. A method of interleaving a sequence of bits by a transmitting device in a wideband code division multiple access (W-CDMA) system, comprising: determining, by an interleaver of the transmitting device, based on a received length of an input vector from the sequence of bits, a nonpruned interleaving vector having a length N, wherein the length N is at least equal to the received length of the input vector; padding, by the interleaver, the input vector; generating, by the interlayer, a pre-pruned interleaved vector having a length equal to the length N, wherein the prepruned interleaved vector is a function of the padded input vector and the non-pruned interleaving vector; and pruning, by the interleaver, one or more elements from the pre-pruned interleaved vector, wherein the pruning further comprises: providing, by the interleaver, a pruned interleaved vector as a portion of the interleaved sequence of bits to a rate matching module of the W-CDMA system; and transmitting, by the rate matching module, a rate-matched version of the interleaved sequence of bits over one or more transport channels to a receiving device.
