Abstract: A base station PDCCH (Packet Data Control Channel) apparatus for scrambling transmission packet data to prevent other terminals from recognizing the transmission packet data in a base station including a packet data channel device for transmitting packet data to a terminal and a packet data control channel device for transmitting control information needed for demodulation of the packet data to the terminal. In the apparatus, an encoder encodes the control information and generates a coded control information stream comprised of a stream of a plurality of bits. A scrambler generates a scrambling sequence using unique information known to only the terminal and the base station, and scrambles the coded control information stream with the scrambling sequence.

Abstract: Disclosed is a reception apparatus and method of a mobile station in a Software Defined Radio (SDR) mobile communication system. A radio frequency (RF) processor converts a received RF signal into a digital signal, and outputs data on a per-unit basis according to a predetermined clock. An external memory stores the output data in a predetermined buffer area. A digital signal processing unit reads stored data samples and performs digital signal processing on the read data samples while storing the data in the external memory is completed.

Abstract: An apparatus and method for receiving control information transmitted from a transmitter using one of a plurality of slot lengths in a high-speed packet transmission mobile communication system is provided. The apparatus and method includes a decoder adapted to receive symbols by the slot, and generate at least one bit stream by decoding as many symbols of at least one possible slot length among a plurality of slot lengths according to a previous decoding result. An error checker adapted to perform error checking on the bit stream from the decoder. A controller is adapted to provide symbols of one more consecutive slot to the decoder, if the error checking failed, and acquire control information from the error checking-passed bit stream, if the error check passed. The decoder is further adapted to output at least one frame quality metric for the bit stream along with the bit stream.
