Abstract  Abstract

High rate CDMA wireless communication is obtained by forming a set of individually gain adjusted subscriber channels. Each channel has a set of orthogonal subchannel codes having a small number of PN spreading chips per orthogonal waveform period. Preferably the set of sub-channel codes are comprised of four Walsh codes each orthogonal to the remaining set and four chips in duration. It is also preferred that pilot data be transmitted via a first transmit channel and power control data transmitted via a second transmit channel. The remaining two transmit channels are used for transmitting non-specified digital data including user data or signaling data or both. One of the two non-specified transmit channels may be configured for BPSK modulation and the other for QPSK modulation.
