Abstract: 본 발명은 적응형 역방향 다이오드 구조를 갖는 전력증폭기에 관한 것으로, 증폭부, 바이어스부 및 역방향 다이오드를 포함한다. 증폭부는 입력 고주파 신호를 선형 증폭하기 위해 적어도 하나 이상의 증폭 트랜지스터를 구비한다. 바이어스부는 증폭부의 베이스 단자와 기준 전압 사이에 연결되어, 증폭부에 대한 기준 바이어스 전압을 공급한다. 역방향 다이오드는 바이어스부와 증폭부에 입력 고주파 신호를 공급하는 구동단 사이에 연결되어, 구동단의 출력 고주파 신호 중 일부를 바이어스부로 커플링시킨다. 본 발명에 따르면, 역방향으로 바이어스된 다이오드가 구동단의 출력전력 세기에 따라 크기가 다른 RF 신호를 커플링시켜 바이어스 트랜지스터에 공급함으로써 전력단의 공급 DC 전류를 출력전력에 따라 적응적으로 공급하며, 이로 인해 작은 출력전력에서는 삽입 손실을 최소화하고 높은 출력전력에서는 높은 선형성을 확보할 수 있다. 또한, 본 발명에 따른 바이어스 회로는 아주 작게 구현될 수 있어 실제적인 단말기 전력증폭기에 용이하게 내장될 수 있다.

Abstract: PURPOSE: A method for determining a priority level for packet transmission and a computer-readable recording medium storing the program are provided to give relative priority levels to packets by using delay time characteristics among different traffic packets and differentiate inter-packet priority levels among the same type of traffic. CONSTITUTION: A scheduler starts scheduling at a specific point(S100). The scheduler measures an SNR(Signal to Noise Ratio) of a user terminal(S210). An amount of data stored in a queue is measured(S310). A extent of a provided service during a certain slot is calculated in consideration of an average transmission data amount(S320). A packet interval is measured based on traffic characteristics of data stored in the queue(S410). A delay available time of a packet is calculated by using the packet interval(S420). A priority level of each packet is determined(S500). Data transmission is performed during a certain time with respect to a queue for a user with the highest priority level(S600).

Abstract: PURPOSE: A scheduling method for processing traffic of multi calls in a wireless communication base station channel card is provided to select one of 8 time segments, and to distribute load of traffic processing, then to efficiently treat traffic processing of the multi calls, thereby efficiently managing the traffic processing as satisfying a 3GPP standard. CONSTITUTION: A scheduling system checks whether an active call exists in an FP DL(Frame Protocol Down Link) database(501). If so, the system brings a frame offset, a chip offset, and a value of a TTI(Transmission Timing Interval) from the call(502). If the chip offset is bigger than one time segment(503), the system sets a frame position to '1'(504). If the chip offset is smaller than one time segment, the system sets the frame position to '0'(505). The system compares a value of a current CEP(Channel Element Processor) is the same as '0'(506). If so, the system decides whether another value is the same as a current time segment value(507). If so, the system processes traffic data with an exclusive channel of the call, and transmits the data to an MDSP(Modulation Digital Signal Processor)(508).
