摘要： Disclosed is a receiver capable of simplifying hardware required for finger and combiner in accordance with the channel characteristics in a 3rd generation mobile communication system using physical channels recommended by the 3GPP (3rd generation partnership project). The rake receiver for the mobile communication system complying with the 3GPP standard includes fingers for performing in parallel a radio signaling of downlink physical channels recommended in the 3GPP standard and inputted through multiple paths in a first-in first-out (FIFO) manner, combiners for summing a certain channel of different time offsets outputted from the fingers with an identical timing, and a selector for controlling the different physical channels outputted from the fingers to be summed by the different combiners, respectively.

摘要： A mobile terminal in a mobile communications system stores received data with less hardware and more power-efficient power requirements compared with conventional terminals. These advantages are achieved by using a single memory to store data decoded by a plurality of decoder units. More specifically, the terminal performs the steps of selecting one of two decoders for decoding data, decoding data in the selected decoder, determining an address of a common memory connected to the two decoders based on information in the decoded data; and storing the decoded data in the address of the common memory. The first decoder may be a viterbi decoder and the second decoder may be a turbo decoder. The common memory addresses may be determined based on the values of predetermined bits of decoded data output from the decoders. By using a common memory for this purpose, the terminal is able to realize a smaller size than could previously be attained.
