Title: An apparatus for receiving a signal in frequency hopping CDMA system
Inventor: KIM JIN YEONG
IPC: H04B7/04
Filed: 2000-10-10
Abstract: PURPOSE: A receiving apparatus for an FH(Frequency Hopping) CDMA(Code Division Multiple Access) system is provided to optimize a packet process rate of an FH CDMA network by applying an adaptive antenna array to a receiving terminal. CONSTITUTION: A plurality of antenna elements(211-21m) are arrayed and installed in an adaptive antenna unit(21) to be separated at half wavelength. An FH local oscillator(22) generates a frequency inverse hopping sequence signal to each user. A plurality of frequency inverse hoppers(231-23m) de-spread signals received through the antenna elements(211-21m) on the basis of the generated frequency inverse hopping sequence signal. A spatial filter(24) corrects the receiving signals de-spreaded through the frequency inverse hoppers(231-23m) according to a variably set weight value(filter coefficient). A delay(25) delays an output signal of the spatial filter(24). An adding and subtracting calculation unit(26) obtains a difference value between the signal delayed by the delay(25) and a reference signal. An adaptive processor(27) estimates an arrival angle of the receiving signal and sets the weight value on the basis of the difference value obtained in the adding and subtracting calculation unit(26). A demodulator(28) demodulates an output signal of the spatial filter(24). An RS(Reed-Solomon) decoder(29) decodes an output signal of the demodulator(28).
