Abstract

In this paper, a novel codebook design method for data modem over voice channel is presented. Proposed method searches the symbols which have the maximum probability distribution overlap in the symbol space and minimizes the overlap to improve the symbol error rate via minimax optimization. We present numerical simulations and an example implementation. We also give the results of the experiment tests.

본 논문에서는 음성 채널을 통해 데이터를 전송하기 위한 데이터 모뎀의 코드북 설계 방법에 대해 기술하였다. 제안한 코드북 설계 방법은 minimax 최적화 기법을 이용하여 탐색 공간에 분포하는 심볼들 중 최대 중첩을 갖는 심볼들의 중첩을 최소화하도록 하는 방법이다. 제안한 방법에 따라 설계된 코드북을 적용한 데이터 전송 시스템을 제시하였으며, 모의 실험과 실제 이동통신망 적용 실험을 통해 제안한 방법의 성능을 평가하였다.
