Abstract
A transceiver arrangement for a smart antenna system of a mobile communication base station is disclosed. A receiving apparatus comprises N array antennas, N AFEUs for down-converting each of signals which are received from the N array antennas into N different frequencies, respectively, N:1 power combiner for combining the converted N signals into one signal, a wideband transceiver for down-converting the combined signal into a base frequency band, a wide band analog-to-digital converter for converting the down-converted signal into a digital signal, N digital filters for dividing the digital signal into N different digital signals and L beam forming modules for receiving one by one the N digital signals divided by each of N digital dividing means and for forming adaptive beam, wherein L is the number of subscribers. A transmitting apparatus comprises L beam forming modules for L subscribers, N signal adders for adding N different signals provided by each of the beam forming modules, N digital modulators for up-converting the signal added by each of the signal adders into different frequencies, respectively, a digital signal combiner for combining signals modulated in the frequency by the N digital modulators into a digital signal, a wide band digital-to-analog converter for converting the digital signal combined by the digital signal combiner into a analog signal, a wide-band transceiver for up-converting in the frequency the analog signal converted by the wide band digital-to-analog converter, a 1:N power divider for dividing a output signal of the wide-band transceiver to N signals, equally, N antenna front-end units (AFEUs), each of AFEUS for converting one of the N signals divided by the 1:N power divider into a transmission frequency, and N array antennas for transmitting a signal from each of the antenna front-end units (AFEUs).
