METHOD AND DEVICE FOR TIME DIVISION MULTIPLE DIRECTION MULTIPLEX COMMUNICATION

摘要

PURPOSE:To handle a wide range terminal speed, to improve receiving efficiency of transmitted signals and to reduce the quantity of hardware by constituting one frame of (n) subframes, and providing (m) kinds from one made by optimizing minimum burst dividing unit of one subframe structure to low terminal speed and subdividing to one made by optimizing to high terminal speed and roughly divided, and enabling to select minimum burst dividing unit. CONSTITUTION:Subframe 64kb/s, 384kb/s setting switch 14 sets n subframes making wireless 64kb/s subframe '1' and wireless 384kb/s subframe '0'. A base band signal from a base band interface is branched by a base band signal branching circuit 15 according to the terminal speed and written in a timing interface frame wireless 64kb/s subframe converting memory 16 or a base band interface wireless 384kb/s subframe converting memory 17 respectively by timing pulses S1, S2.
