BASE STATION USING LOW POWER INTERFERENCE CODE POWER MEASUREMENT, PARTICULARLY FOR MEASURING INTERFERENCE SIGNAL CODE POWER IN A WIRELESS HYBRID TDMA/CDMA COMMUNICATION SYSTEM

摘要

PURPOSE: A base station using low power ISCP(Interference Signal Code Power) measurement is provided to lengthen durability of a battery of a UE(User Equipment) by providing low power ISCP computation. CONSTITUTION: An antenna(10) receives a signal transmitted in a specific time slot in a wireless hybrid TDMA/CDMA format. An AGC(Automatic Gain Controller)(12) coupled to the antenna(10) controls a power level of the transmitted reception signal. A mid-amble processing unit(16) processes a reception mid-amble of the transmitted reception signal. A look-up table(22) provides correlation between an ISCP value and a gain value. A low power ISCP computation unit(20) coupled to the look-up table(22), to the mid-amble processing unit(16) and to the AGC(12) computes an output of the mid-amble processing unit(16), a gain value of the AGC(12) and an estimated ISCP, and uses the correlation between the ISCP value and the gain value. A sampling unit(14) coupled to the AGC(12) and to the mid-amble processing unit(16) samples the transmitted reception signal.
