摘要： An apparatus and method for reading written symbols by deinterleaving to decode a written encoder packet in a receiver for a mobile communication system supporting turbo coding and interleaving, such that a turbo-coded/interleaved encoder packet has a bit shift value m, an up-limit value J and a remainder R, and a stream of symbols of the encoder packet is written in order of column to row. The apparatus and method perform the operations of generating an interim address by bit reversal order (BRO) assuming that the remainder R is 0 for the received symbols; calculating an address compensation factor for compensating the interim address in consideration of a column formed with the remainder; and generating a read address by adding the interim address and the address compensation factor for a decoding-required symbol, and reading a symbol written in the generated read address.

摘要： Provided is an apparatus and method for canceling an interference signal in a packet data receiver in which data is transmitted and received over a packet data channel and a packet data control channel. The packet data channel is time-synchronized with the packet data control channel. A buffer temporarily stores a signal on the packet data channel, combined after being received through multiple paths, until the packet data control channel is decoded. An interference cancellation controller analyzes packet data control channel information obtained by decoding the packet data control channel, and outputs an interference cancellation command signal only when it is determined that effective packet data to be received exists in a current time slot. An interference cancellation section receives the packet data channel signal output from the buffer, and cancels an interference signal from the packet data channel signal only when the interference cancellation command signal is received.

摘要： An apparatus and method for compensating the gain of an Automatic Gain Controller (AGC) for stabilizing the reception power of discontinuously transmitted packet data in a mobile communication system are disclosed. A compensation controller receives an AGC value from the AGC, sampling the AGC value by a predetermined sample number for a predetermined period, and obtains an AGC compensation gain by comparing a predetermined value with the difference between a sampled AGC value with a reference gain for the predetermined period. A compensator compensates the AGC value with the AGC compensation gain, thereby correcting errors generated in view of the nature of the AGC.

摘要： Disclosed is a system and method for demodulating packet data channels with multiple Walsh codes in a CDMA mobile communication system supporting voice and packet data services. A plurality of fingers process signals received from a transmitter as inputs, perform despreading and channel compensation with spreading codes pre-assigned to the transmitter, and outputting the despread chip signals. A chip combiner combines the chip signals output from the plurality of fingers. A chip buffer stores the combined chip signals until decoding of the packet data control channels is completed and information on the multiple Walsh codes assigned to the packet data channels. Then, a multiple Walsh demodulator generates at least one Walsh symbol performing Walsh decovering of the combined chip signals using information on the multiple Walsh codes. Therefore, the system can efficiently demodulate data transmission channels using the multiple Walsh codes, and thus complexity of the system and demodulation time can be reduced.

摘要： A method and apparatus for mapping a stream of bits output from an encoder to a stream of bits for 2m-ary modulation. The method and apparatus divides the stream of bits from the encoder into a first period and a second period. The first period includes bits with higher priority in the stream of the bits output from the encoder, and the second period includes bits with lower priority. The method and apparatus maps the bits existing in the first period to bit positions with higher reliability in a stream of m bits representing each of the bits for 2m-ary modulation, and maps the bits existing in the second period to bit positions with lower reliability in the stream of m bits.

摘要： A handoff method and apparatus for a terminal based on efficient set management. A pilot search rate for base stations of a neighbor set is increased, thereby preventing a failure to perform a necessary idle handoff or a failure to receive a paging message for a call connection. A terminal checks if it is in an idle state or in a traffic state, and measures the pilot energy of the BS of the active set and the pilot energy of a BS of the neighbor set with different pilot measurement patterns according to the checked state. The terminal measures the pilot of the BS of the active set and the pilots of at least one BS of the neighbor set while in the idle state. The terminal in the idle state operates in a sleep mode upon reception of information indicating that there is no paging channel, thereby minimizing its power consumption.

摘要： Disclosed is a receiving apparatus of a Wireless Broadband (WiBro) system and a method for processing an Automatic Repeat reQuest (ARQ) block for the same. In the receiving apparatus, ARQ blocks are grouped and are then processed by the group, thereby greatly reducing memory resources and overhead processing time, which is required in a case where the respective ARQ blocks are processed separately. Also, the generation of unnecessary purge timers in a receive (Rx) window of the receiving apparatus is reduced, thereby enabling the reduction of costs according to the operation of purge timers.
