ABSTRACT:
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.
