Abstract: A plurality of communication signals have differing spreading codes. Each communication has an associated code comprising chips. For each chip of each communication, a vector of that chip convolved with an impulse response is produced. For each communication, support blocks comprising the chip vectors are produced. A number of the chip vectors in a support block is based on that communication's spreading factor. A system response matrix is assembled. The system response matrix has symbol sub-matrices. Each symbol sub-matrix comprises a support block from each communication. Data of the communications is detected using the symbol response matrix.
