Abstract:
A mobile terminal, comprises: a case including a conductive metal part; a main board mounted inside the case and having a power supply part and a ground surface; a first antenna radiator disposed so as to be spaced from the power supply part to the first antenna radiator; a power supply line for electrically connecting the power supply part to the first antenna radiator and ground line for electrically connecting the ground surface to the metal part and the first antenna radiator, thereby preventing a decrease in the performance of an antenna since the formation of an electromagnetic field between the case of a metallic material and the main board can be minimized even if the metallic material is used for the case.
Abstract:
A communications system includes a receiver unit connected with a transmission channel. The receiver unit determines a signal power of a first communications signal received over the transmission channel. A transmitter unit is connected with the transmission channel and transmits a second communications signal, wherein a gain of the communications signal being output by the transmitter unit is controllable. A control unit controls the gain of the transmitter unit in response to the determined signal power. At the receiver unit, detection of broadcast signal ingress during data communication is improved and methods for avoiding disturbances between coexisting communications systems may become more reliable. Different distances between successive training symbols suitable for channel estimation may be provided to enhance the noise measurement.
Abstract:
A method, including receiving an input analog signal containing noise at a specific noise frequency and digitizing the input analog signal to form a digitized signal. The method also includes recovering a first amplitude and a first phase of the noise from the digitized signal, and generating an analog correction signal at the specific noise frequency. The analog correction signal has a second amplitude equal to the first amplitude and a second phase opposite to the first phase. The method further includes summing the input analog signal with the analog correction signal to generate an output analog signal.
