Abstract:
The present invention relates to a method, for receiving an additional network service which is provided through a temporary base station which is temporarily or locally arranged for transmitting disaster information, which includes: a step of receiving information for the additional network through an existing network service provided by a base station; a step of confirming if a service is to be converted to the additional network or not based on information for the additional network; and a step of receiving an additional network service through the additional network. According to the present invention, a temporary or local additional network service can be efficiently provided in a wireless broadcasting network/communication network. According to the present invention, a communication service can be provided through an additional network although a communication service failure is occurred due to traffic explosion in a region which a disaster or an event and et cetera is generated in a communication service point of view and a broadcasting channel which provides information specialized to the disaster or the event is temporarily or locally additionally provided in a broadcasting point of view.

Abstract:
PURPOSE: An equalizer for a hierarchically modulated signal is provided to improve the performance of an apparatus receiving the hierarchically modulated signal, by reflecting the characteristics of the hierarchically modulated signal. CONSTITUTION: A forward filter (1210) generates a forward filter output signal by filtering a hierarchically modulated signal. A hierarchal symbol detector (1220) detects a first hierarchical symbol value from a first hierarchical symbol detector input signal. A feedback filter (1230) generates a feedback filter output signal by filtering a value obtained by adding a second hierarchical symbol value to the first hierarchical symbol value. The first hierarchical symbol detector input signal is the sum of the forward filter output signal and the feedback filter output signal. Each tap coefficient of the forward filter and the feedback filter is updated on the basis of an error signal acquired by comparing the value of the first hierarchical symbol detector input signal with the value obtained by adding the first hierarchical symbol value and the second hierarchical symbol value. [Reference numerals] (1210) Forward filter; (1220) First hierarchical symbol detector; (1230) Feedback filter; (AA) Decoder output signal; (BB) Lamp output signal; (CC) First hierarchical symbol; (DD) Signals; (EE) Second hierarchical symbol

Abstract:
PURPOSE: A ranging UL signal pre-distortion system and method are provided to reduce the detection time of a ranging UL signal in a BS or a RS. CONSTITUTION: A signal receiving unit(310) receives a signal from the upper node of one of a BS(Base Station) or a RS(Relay Station). A channel gain estimation unit(320) presumes channel gain for a channel with a received DL(DownLink) signal. A signal distortion unit(330) distorts an UL(UpLink) signal in consideration of the estimated channel gain. A signal transmitting unit(340) transmits the distorted UL signal to the upper node. A channel compensation unit(350) compensates the received signal in consideration of the estimated channel gain.
