Abstract: An apparatus and a method for mapping a connection identifier in a mobile communication system are provided to process mass data at high speed, and to easily modify information related to the connection identifier. An apparatus for mapping a connection identifier includes a host processor(410), a memory controller(420), a DSP(Digital Signal Processor,430), and an FPGA(Field Programmable Gate Array,440). The host processor searches for a connection identifier matched with an IP packet which is received from a PAR(Packet Access Router,130) located at a higher level and is stored in a memory(20) by controlling the memory controller. Then, the host processor maps the connection identifier with the IP packet, and performs a higher level MAC(Media Access Control) function including at least one between an IP packet scheduling and a resource assignment function. The DSP receives the IP packet mapped with the connection identifier via a PCI bus from the host processor, and performs a lower level MAC function including at least one of a packet encoding and a CRC(Cycle Redundancy Check) generation and checking function. The FPGA receives the IP packet mapped with the connection identifier via the PCI bus from the DSP and performs a high speed and time restrictive lower level MAC function including at least one between an IP packet HEC(Header Error Control) generation and checking function. The memory controller matches the first information with the second information one to one, stores the matched information and cyclically updates the first and the second information. The memory controller searches for the second information matched with the first information of the IP packet in the memory and provides the second information for the host processor.

Abstract: An apparatus and a method for canceling successive multiple interferences in a mobile communication system are provided to enhance definiteness in estimating channels, performance of a CDMA type mobile communication system, and system capacity by accommodating more number of users. A method for canceling successive multiple interferences comprises the following steps. One diffuser of a transmitter diffuses a signal of a pilot channel by using the Walsh code 0(S410), and other diffuser diffuses (+1, -1) signals of an i-th user in a communication channel by using the Walsh code 1(S420). An adder adds the signal of the pilot channel and the user signal, and generates a transmission signal(S430). Another diffuser diffuses the generated transmission signal by using the PN(Pseudo-random Noise) code(S440). A pulse shaping filter performs a pulse shaping and filtering operation on the transmission signal(S450). A modulator performs a frequency modulation operation on the transmission signal, outputted by the pulse shaping filter, by using a carrier wave(S460).

From received signals containing user signals and pilot signals, the controller extracts a plurality of user signals corresponding to a pilot signal having a BER(Bit Error Rate) larger than the first reference value and an SNR(Signal to Noise Ratio) larger than the second reference value. The noise cancelers respectively comprise combiners(250-250n), respreaders(260-260n), and multipliers(270-270n). Based on the extracted user signals, the noise cancelers respectively remove noise from the received signals.
