Abstract: PURPOSE: An encoding device and method using a turbo signal, a permutation switching device and permutation switching technique are provided to largely improve an error correction performance of a transceiving data by applying a permutation switching technique and a puncturing technique. CONSTITUTION: A first encoder(101) outputs a first parity bit by encoding a three bit received from a first to a third block which is comprised of each N numbers of bit. A permutation substituent(200) permutation substitutes the three bit. A second encoder(102) outputs a second redundant bit by encoding the substituted three bit. A puncturing device(300) controls the signal rate by selectively removes a first redundant bit and a second redundant bit by considering an encoding rate of a preset turbo signal.

Abstract: The present invention relates to a frequency mixer utilized in a transceiver of radio frequency band. The frequency mixer for a radio frequency transceiver, includes two NMOS transistors, which are commonly connected, for generating a mixed signal combined with even harmonics, wherein a first end of the NMOS transistors is input a radio frequency signal, a second end of the NMOS transistors outputs the mixed signal, and gates of the NMOS transistors receive differential signals of local oscillator. The frequency mixer needs only half local oscillation frequency and a fundamental frequency of local oscillator is not presented. Therefore, the present invention can prevent generation of DC Voltage offset and also reduce frequency of local oscillator by half when it is utilized in a heterodyne transceiver.
