Problems solved by technology

[0016] That is, since the degradation of the GSM transmission signal is not very high when BPF is used, the conventional GSM mobile phone has such a problem that the reception sensitivity of DVB-H broadcasting is caused due to the transmission signal flowing into the DVB-H receiver 12 as noise. deterioration

Embodiment Construction

[0042] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] FIG. 4 is a schematic structural diagram of a mobile terminal according to an exemplary embodiment of the present invention. With reference to Fig. 4, mobile terminal comprises: GSM transmitter / receiver 100, is used for transmitting and receiving GSM signal by first antenna ANT1; DVB-H receiver 200 for receiving DVB-H signals through the second antenna ANT2; and phase noise reduction device 300 for extracting low power signals by inverting the first signal coupler 110 The phase of the phase noise signal corresponding to the DVB-H reception frequency band and combining the phase noise signal and the DVB-H signal received through the second antenna ANT2 to reduce the GSM transmission signal included in the signal received through the second antenna ANT2 phase noise signal. In this case, the DVB-H receiver 200 may correspond to the second R...

Abstract

A mobile terminal capable of breaking a phase-noise signal caused by a high power transmission signal of a mobile phone such as GSM when receiving digital TV broadcasting such as DVB-H and a method of reducing interfering phase-noise in the mobile terminal. The mobile terminal includes a first RF transmitter / receiver; a first signal coupler; a phase-noise filter; a phase shifter; a VGA amplifier; and a signal combiner.

Description

[0001] This application claims priority from Korean Patent Application No. 2006-43872 filed with the Korean Intellectual Property Office on May 16, 2006, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a mobile terminal capable of receiving digital TV broadcasts, and more particularly to a mobile terminal and a method for reducing interference phase noise. Among them, the mobile terminal is capable of attenuating a phase noise signal caused by a high-power transmission signal of a mobile phone such as GSM when receiving a digital TV broadcast such as DVB-H, preventing digital TV broadcasting caused by a phase noise signal of a high-power GSM signal degradation of receiving sensitivity, and improving the receiving performance of digital TV broadcasting such as DVB-H, and enabling mass production. Background technique [0003] In general, much attention has been paid to digital TV broadcasting recentl...
