Claim:
1. A computer-implemented method, comprising: receiving a signal comprising communication data from two or more mobile devices, wherein each of the two or more mobile devices is identifiable by an associated pseudonoise sequence, and wherein a first mobile device of the two or more mobile devices is identifiable by an associated first pseudonoise sequence; storing two or more samples of the received signal in an input register; storing a segment of the first pseudonoise sequence as a bit vector in a second register wherein the segment comprises a sequence of data elements of the first pseudonois sequence, each data element of the segment represented by no more than two bits in the bit vector, and wherein the sequence of data elements occupies sequential bit positions within the second register; and processing a single instruction multiple data (SIMD) instruction, by an SIMD processor, to produce correlation values associated with the segment of the first pseudonoise sequence in the second register and the two or more samples of the received signal in the input register; wherein the processing of the SIMD instruction comprises distributing the bit vector representing the segment of the first pseudonoise sequence in the second register across two or more lanes of the SIMD processor, wherein a first data element of the sequence of data elements stored in the bit vector is assigned to a first lane of the SIMD processor and a second data element of the sequence of data elements stored in the bit vector is assigned to a second lane of the SIMD processor, and wherein the first lane and the second lane are distinct from each other; and wherein the processing of the SIMD instruction contributes to despreading the received signal, and wherein an output of the processing of the SIMD instruction comprises at least a portion of the communication data from the first mobile device.
