Abstract: PROBLEM TO BE SOLVED: To provide an excellent and improved method and apparatus for high rate CDMA wireless communication.
SOLUTION: A set of individually gain adjusted subscriber channels are formed via the use of a set of orthogonal subchannel codes (W
i ) having a small number of PN spreading chips per orthogonal waveform period. Data to be transmitted via one of the transmit channels is low code rate error correction encoded, and a repeated sequence is subjected to gain adjustment and summed with data modulated using the other subchannel codes. The resulting summed data before being modulated with one of the subchannel codes is modulated using a user long code and a pseudo-random code (PN code) and upconverted for transmission.

Abstract: In a communication system capable of variable rate transmission, scheduling of high speed data transmission improves utilization of the forward link and decreases the transmission delay in data communication. Each remote station is assigned one primary code channel for the duration of the communication with a cell. Secondary code channels of various types and transmission capabilities can be assigned by a channel scheduler for scheduled transmission of data traffic at high rates. Secondary code channels are assigned in accordance with a set of system goals, a list of parameters, and collected information on the status of the communication network. Secondary code channels can be grouped into sets of secondary code channels. Data is partitioned in data frames and transmitted over the primary and secondary code channels which have been assigned to the scheduled user.

Abstract: A method for demodulating a received signal comprising complex multiplying (202,204) the received signal by a complex pseudonoise code to produce a complex pseudonoise despread signal (XI,XQ); filtering (214) the complex pseudonoise despread signal to provide a complex filtered pilot signal; multiplying (210) the complex pseudo-noise despread signal by a first demodulation code to provide a first complex demodulated data signal; and phase rotating and scaling (216,218) the first complex demodulated clara signal in accordance with the complex-filtered pilot signal to provide a first soft decision data.
