Time shared ?? channels direct conversion receiver, and method therefor.

The present invention relates to that, in particular, a direct conversion (direct conversion) method by a direct conversion receiver and a direct conversion reception method (Direct Conversion Receiver) adopted for a receiver used in a wireless terminal in a wireless communication environment. Direct conversion receiver (DCR) according to the present invention, a local oscillator (LO) for generating a sine wave signal; Mixer (mixer) for synthesizing the sine wave signals received by receiving the signal and the signal which is input from the local oscillator; An analog-to-digital converter (ADC) for converting the mixed analog signal into a digital signal; And a digital signal processor (DSP) for outputting separately the converted digital signal into an I channel and a Q channel and transmits the phase information of the sine wave to be the local oscillator (LO) supplied to the local oscillator (LO) . Use jeokjeop conversion receiver (DCR) according to the present invention resolve the mismatch between the I channel and the Q channel, there is an effect to obtain a good efficiency and yield (yield) in the digital system of the high data rate (data rate).
