Random access communication method by use of CDMA, and system for mobile stations which use the method

摘要

A plurality of mobile stations share a plurality of spreading codes for random access use at the same frequency and randomly select the spreading codes for each signal sequence, for each message, or for each burst, by which the possibility of signals clashing with each other can be reduced; accordingly, even if the same spreading code is used as a channel for which a number of mobile stations compete, the throughput can substantially be improved in the packet signal transmission or control channel. <IMAGE>
