MOBILE COMMUNICATION SYSTEM

A mobile communication system includes a demodulator demodulating an interleaved data signal and outputting a demodulated data. A deinterleaver data array receives and deinterleaves the demodulated interleaved data and outputs a deinterleaved demodulated data. A memory stores the deinterleaved demodulated data and a Viterbi decoder receives the deinterleaved demodulated data from the memory. The Viterbi decoder corrects any error in the deinterleaved demodulated data. A controller accesses unit data outputted from the demodulator to the deinterleaver data array and the memory, respectively. An address generator receives an externally applied start address signal and outputs address signals corresponding to a block size to the deinterleaver data array. An input/output unit is coupled to the demodulator, the deinterleaver data array, and the controller. The input/output unit controls data input/output operations.
