Abstract
A spread spectrum communication apparatus for transmitting multiple signals such that signals transmitted from several transmitter-receivers can have the same PN code and yet not interfere with each other. A phase controller is used to control the phases of the PN codes from multiple transmitters so that the PN code phase is different for each transmitter. Thus, even though the same PN codes are transmitted, they all have different phases to prevent interference. This arrangement reduces the number of PN codes needed since only one PN code generator is needed for several receiver blocks.
