Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a high data rate CDMA interface with improved bandwidth efficiency that is a subscriber unit capable of carrying out a plurality of types of communication.

SOLUTION: A set of individually gain adjusted subscriber channels (A B C Pilot) are formed via the use of a set of orthogonal subchannel codes (Walsh+- Walsh++--) having a small number of PN spreading chips per orthogonal waveform period. Data to be transmitted via one of the transmit channels are low code rate error correction encoded and sequence repeated before being modulated with one of the subchannel codes gain adjusted and summed with data modulated using the other subchannel codes. The resulting summed data are modulated using a user long code and a pseudorandom spreading code and upconverted for transmission.
