Abstract: A method and an apparatus for receiving broadcasting service information in a digital broadcasting system are provided to realize PSI/SI packet data optimized to processing capability of a controller and prevent overuse of a memory by selecting only PSI/SI designated by the controller and controlling the number of packets to be transmitted or a transmission time, thereby reducing power consumption of a DVB(Digital Video Broadcasting)-H receiver. A PID(Packet Identifier) filtering unit detects PSI/SI(Program Specific Information/Service Information) coinciding with a preliminarily set PID value from a received transport stream. A packet counter counts the number of the detected PSI/SI. A controller sets up a PID value for performing PID filtering to the transport stream packet, and reads the PSI/SI if the counted number of the PSI/SI reaches a preliminarily decided number.

Abstract: PURPOSE: A method for controlling a turbo-decoding period in high rate packet data system is provided to perform efficiently a process for decoding received sub-packets by using only one turbo decoder. CONSTITUTION: A turbo decoder performs a decoding process for a packet data channel signal according to a demodulated value when the packet data channel signal is demodulated(600-604). A period of an encoding process for an ACK/NAK response of the packet data channel signal is compared with a period of a decoding process of the packet data channel signal(606-608). The decoding process is stopped if the encoding process for an ACK/NAK response of the packet data channel signal is performed before the decoding process of the packet data channel signal(610-614).

Abstract: PURPOSE: A turbo interleaver unit of a mobile communication system using a turbo code and a method thereof are provided to reduce a time for an interleaving process by simplifying a calculation process of parameters for performing the interleaving process. CONSTITUTION: A turbo interleaver unit of a mobile communication system using a turbo code includes a modulo operation unit and a prime generation unit(400). The modulo operation unit receives a particular value determined by a size of an interleaver and outputs a residual value by performing a modulo operation. The prime generation unit(400) checks output values of the modulo operation unit and outputs the particular value as a turbo interleaving parameter if the output values are equal to the residual value.

Abstract: 본 발명에 의한 (4, 20) RLL 코드 생성방법 및 장치에서 생성된 변조코드의 검출창폭은 기존의 (1, 7) RLL 변조코드(2/3Tb)에 비하여 46% 감소한 반면 기록밀도비는 37% 증가함으로써 기존의 (1, 7) RLL 변조코드보다 고밀도의 기록이 가능하고, 스펙트럼이 (1, 7) RLL 변조코드에 비해 저주파 대역에 집중해 있기 때문에 높은 신호대 잡음비(SNR)를 갖게 된다. 또한, 가변부호어길이를 갖는 VFM과는 달리 고정보호어길이의 변조코드이므로 엔코더와 디코더의 하드웨어 구현이 용이하다.
