Abstract:
Disclosed is a dual band receiver which includes an analog-to-digital converter configured to convert a dual band analog RF signal into a dual baseband digital signal; and a first signal extractor configured to generate a first path signal and a second path signal from the dual baseband signal and to extract a first baseband signal using a relative sample delay difference between the first and second path signals, wherein the dual baseband signal includes the first baseband signal and a second baseband signal, the first path signal is a signal obtained by sample delay of the dual baseband signal and then down sampling of a resultant signal, and the second path signal is a signal obtained by down sampling of the dual baseband signal without sample delay.
Abstract:
Disclosed is a method for detecting cell camp-on and camp-off of a mobile terminal, in which a base station provides an effective zone based service by directly and simply detecting small cell camp-on and camp off of the mobile terminal without a help from a core network, that is, without a separate NAS message under a small cell environment of a mobile communication system by enhancing a tracking area update request processing scheme of the mobile terminal.
Abstract:
Provided are multiple polarized input multiple output system and method for wireless communication which are capable of simultaneously transmitting respective data streams to a plurality of users by transmitting from multiple polarized input to multiple output in proportion to the number of polarized antennas or the number of polarizations used in a transmitter.
