    摘要： A preamble generating method which includes computing (N) chaotic samples; transforming the (N) chaotic samples into (N) binary values of certain bits, respectively, and computing a chaotic sequence bit successively using the (N) binary values; and generating a preamble based on the chaotic sequence bit. By using the sequence bit from the chaotic samples, a plurality of preambles with optimum auto-correlation and cross-correlation properties is generated.

    摘要： A signal reception apparatus and method for communication systems. The signal reception apparatus for communication systems according to the present invention is applicable to communication environments in which a plurality of sub-bands having different frequency bands are sequentially used for communications. An embodiment of the invention has a multi-band index generation unit, a multi-band frequency generation unit, a multiplication unit, a correlation signal reception unit, and a buffer unit. The multi-band index generation unit generates a multi-band index corresponding to a sub-band to which a received signal is transmitted in correspondence with the multi-band index. The multiplication unit outputs a signal obtained by multiplying the received signal by the multi-band frequency. The correlation signal reception unit integrates and outputs the signal of the multiplication unit based on an integral time set in correspondence with the multi-band index. Further, the buffer unit buffers the signal of the correlation signal reception unit to be outputted at a predetermined data rate.

    摘要： A transmission method based on a Hybrid Automatic Repeat Request (HARQ) scheme for in a communication system. A codeword is generated using a Low Density Parity Check (LDPC) code. Parity bits of the codeword are classified on a basis of a transmission priority. Parity bits with an identical transmission priority are grouped. An information bit group of the codeword and parity bit groups with the identical transmission priority are shuffled in a predefined pattern. A packet is generated from the shuffled information bit group and the shuffled parity bit groups based on the transmission priority. The generated packet is retransmitted in response to a retransmission request. The transmission method can obtain the effect of channel interleaving by setting a transmission priority according to importance of puncturing target blocks, shuffling blocks with the same priority, and shuffling and transmitting bits configuring each block.

    摘要： An ultra wideband (UWB) wireless transmitter includes a first pulse generator for modulating data to be transmitted and outputting a first linear modulated signal, a second pulse generator for modulating the data to be transmitted and outputting a second linear modulated signal, an adder for adding the first and the second linear modulated signals, a pulse shaper for shaping the signal output from the adder, a carrier generator for outputting a carrier, a mixer for mixing the signal output from the pulse shaper with the carrier, a transmission unit for transmitting the signal output from the mixer, and a controller for controlling the modulation of the signal to be transmitted by controlling the operation of the first and the second pulse generators and the carrier generator. As a result, a data transmission rate can be greatly increased with very little inter-pulse interference even when the pulse intervals are reduced.
