High data rate CDMA wireless communication system

Abstract

A novel and improved method and apparatus for high rate CDMA wireless communication is described. A set of individually gain adjusted subscriber channels are formed via the use of a set of orthogonal subchannel codes. The set of sub-channel codes are comprised of four Walsh codes. The pilot data and control data are combined onto one channel. The remaining two transmit channels are used for transmitting non-specified digital data including user data or signaling data, or both.

We claim:  
     
         1 . A method for generating modulated data for transmission from a subscriber unit to a base station, the method comprising: 
 combining a pilot signal with a control signal to produce first channel data;    multiplying a first data signal with a first code, said first code being orthogonal to said pilot signal, to produce second channel data;    performing complex multiplication of said first channel data and said second channel data with a complex pseudonoise (PN) code, said complex PN code comprising an in-phase PN code and a quadrature-phase PN code.
