Abstract  Abstract

Set of individually gain-adjusted subscriber channels (A, B, C, Pilot) by using a set of orthogonal subchannel codes (Walsh +-, Walsh ++-) with a small number of PN spreading chips per orthogonal waveform period. Is formed. The data transmitted on one of the transport channels is low code rate error corrected encoded, sequence repeated, gain adjusted, and summed with data modulated using the remaining lower channel codes before being modulated with any of the lower channel codes. . The resulting aggregated data 316 is modulated using a user long code and a pseudorandom spreading code (PN code) and upconverted for transmission. By using short orthogonal codes, it is possible to significantly suppress interference while repeating and extended error correction coding for time diversity to overcome the Rayleigh fading commonly encountered in terrestrial wireless systems. The set of lower channel codes consists of four Walsh codes that are orthogonal to each other. Using four lower channel codes allows for the use of short orthogonal codes but is preferred but the use of a larger number of channels and so longer codes can be employed. Preferably, the pilot data and the control data are combined into one channel. The other two transmission channels are used to transmit unspecified digital data, including user data or signal data, or both.
