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.

1. A method for receiving a signal transmitted by a subscriber unit to a base station comprising:filtering in-phase receive samples to produce a filtered in-phase pilot phase reference signal; filtering quadrature-phase receive samples to produce a filtered quadrature-phase pilot reference signal; multiplying the in-phase receive samples by a first short Walsh cover having a duration of fewer than sixty-four chips per orthogonal waveform period to produce a first in-phase channel signal; multiplying the quadrature phase receive samples by the first short Walsh cover to produce a first quadrature phase channel signal; summing the first in-phase channel signal over the duration of the first short Walsh cover to produce a summed first in-phase channel signal; summing the first quadrature-phase channel signal over the duration of the first short Walsh cover to produce a summed first quadrature-phase channel signal; multiplying the filtered in-phase pilot phase reference signal by the summed first in-phase channel signal to produce a first in-phase product; multiplying the filtered quadrature-phase pilot phase reference signal by the summed first quadrature-phase channel signal to produce a first quadrature-phase product; and adding the first in-phase product to the first quadrature-phase product to produce a first phase rotated signal.
