Patent ID: 8588277

Claim:
A method of generating data for transmission from a subscriber unit to a base station, the method comprising: modulating, at the subscriber unit, each of a plurality of channels of data with an associated code to produce a plurality of streams of modulated symbols, wherein the modulating comprises: multiplying a user first channel data with a first code to produce a first stream of the modulated symbols, wherein one channel of the user first channel data is a BPSK channel and is designated for transmission of voice data; multiplying a user second channel data with a second code to produce a second stream of the modulated symbols, wherein one channel of the user second channel data is a QPSK channel and is designated for transmission of digital data; combining the first stream of the modulated symbols and the second stream of the modulated symbols to generate a combined stream; and complex multiplying the combined stream with one or more pseudorandom spreading codes to generate a complex multiplication result for transmission over a bandwidth; and filtering and upconverting a set of modulated symbols from the complex multiplication result to a carrier frequency for transmission from the subscriber unit to the base station.
