摘要： A system and method for effectively providing an adaptive modulation scheme and known-cyclic prefix (CP) technology in an orthogonal frequency division multiplexing (OFDM) communication system. An OFDM transmission system variably generates a known CP while considering a channel state. Pilot subcarrier position information for generating the known CP is sent to a transmitter. Pilot subcarriers are selected on the basis of a channel state of an OFDM symbol through which data is transmitted and the known CP is generated, such that data transmission is provided efficiently.

摘要： Disclosed is a transmission/reception apparatus and method for providing compatibility between Code Division Multiple Access (CDMA) and Orthogonal Frequency Division Multiplexing (OFDM) in a forward link. The proposed transmission/reception apparatus and method uses a traffic channel based on OFDM while using a pilot channel and a sync channel used in the CDMA scheme. Thus, a transmitter adds a pilot channel signal and a sync channel signal to OFDM-modulated symbols before transmission, and a receiver acquires a pilot channel signal and a sync channel signal, and removes them from a received signal, thereby outputting only pure OFDM-modulated symbols.

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： A low density parity check (LDPC) code generating method and apparatus are provided. A parity check matrix with (N−K) rows for check nodes and N columns for variable nodes are formed to encode an information sequence of length K to a codeword of length N. The parity check matrix is divided into an information part matrix with K columns and a parity part matrix with (N−k) columns. The parity part is divided into P×P subblocks. P is a divisor of (N−K). First and second diagonals are defined in the parity part matrix and the second diagonal is a shift of the first diagonal by f subblocks. Shifted identity matrices are placed on the first and second diagonals and zero matrices are filled elsewhere. An odd number of delta matrices each having only one element of 1 are placed in one subblock column of the parity part matrix. The parity check matrix is stored.

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.
