    摘要： An apparatus and method for improving antenna diversity in a receiver of a broadband wireless communication system using multiple antennas are provided. The receiver with the diversity apparatus uses a structure of multiple analog front ends, a structure for measuring antenna-by-antenna reception power values/Carrier-to-Interference plus Noise Ratios (CINRs) after Fast Fourier Transform (FFT) using a single analog front end, and a structure based on a single analog front end for measuring antenna-by-antenna reception power values after Analog-to-Digital (A/D) conversion without use of FFT. When a receive antenna is selected, the measured reception power values/CINRs are used. In a system for transmitting pilot signals with preamble data in a regular pattern, the receiver can have improved performance through a suitable frequency modulation process and can be implemented at low cost, as compared with that of the conventional antenna selection diversity.

    摘要： An apparatus and method is provided to process a digital signal in an orthogonal frequency division multiple access (OFDMA) wireless communication system. In the apparatus, a memory stores the number of subcarriers allocated to a mobile terminal and stores an inverse discrete Fourier transform (IDFT) coefficient. A controller outputs a mode selection signal indicating a transmission mode or a reception mode. An inverse fast Fourier transform (IFFT) block multiplies a first result obtained by determining a bitwidth for the IDFT coefficient according to the number of subcarriers by a second result obtained by determining a bitwidth for data according to the number of subcarriers.
