METHOD AND DEVICE FOR CONSTRUCTING TD-LAS SYSTEMS

摘要

A method of constructing a TD-LAS system, comprises the step of: using the LAS code as spread spectrum multiple Address code; using the LA code and the LS code to perform the establishment of the network in cells; the radio frame construction is comprised of the LA code and the LS code; the access pulse of uplink synchronization is based on LS code; the sub-frame of downlink synchronization is formed of the LA code and the LS code. The invention also provide a device for constructing a TD-LAS system, comprised of a transmitter and a receiver, wherein the said transmitter includes at least a spread spectrum means, which uses LAS code as spread spectrum multiple address code; the said receiver includes at least a de-spread means, which uses the LAS code as spread spectrum multiple address code; the information from source is at least spreaded by a spread means and sent to the channel, wherein the spread means uses the LAS code as spread spectrum multiple address code; the information received by sink has at least been de-spreaded by a de-spread means, in which the spread spectrum multiple code is based on the LAS code.
