Abstract: Provided is a method and apparatus improving a deterioration of a gain flatness and a phase characteristic that may be incurred while a baseband signal is transformed into a immediate frequency (IF) signal and a radio frequency (RF) signal in a broadband wireless communication system. A sub-band extractor may divide the broadband signal into multiple sub-band signals, may pre-compensate for a gain and a phase delay of each sub-band signals in the baseband, and may combine the pre-compensated sub-band signals into the single broadband signal and thus, the deterioration of the gain flatness and a phase delay flatness that may be incurred while the broadband signal is transformed into the IF signal and the RF to signal, may be improved.

Abstract: PURPOSE: A recursive type half band filter and a filtering method using the same are provided to replace multilevel half band filter with one half band filter. CONSTITUTION: A recursive type half band filter (100) comprises a first storing part (110), a second storing part (120), a calculating part (130), and a controlling part (140). The first storing part controls first input data among a plurality of input data composed of first input data and second input data, which are sequentially repeated at least once, to be impeded prior to be stored before second input data is inputted. The second storing part stores second input data. The calculating part multiplies the second input data with a predetermined filter coefficient before adding to the first input data, which is stored at the first storing part, for producing output data. Whether the output data is predetermined final output data allows the controlling part to determine the output data as final output data or as new input data. [Reference numerals] (110) First storing part; (120) Second storing part; (130) Calculating part; (141) Input controlling part; (142) Output controlling part; (143) Calculation stage control part; (144) Address control part

Abstract: PURPOSE: A method for recovering failure in a directed diffusion routing protocol is provided to rapidly recognize the occurrence of a failure when the failure happens in a path transmitting data and to recover the failure promptly. CONSTITUTION: A first node transmits the data to a second node(S210), and the second node is different from the first node. If an ACK code is not received from the second node(S220), the first node re-transmits the data to a third node(S230). The third node is different from the first and second nodes. The first and second nodes are located on a reinforced path.
