실내 무선 환경의 PPM-TH와 PAM-DS UWB 시스템에서 시공간 블록 부호의 성능 분석

A space time code (STC) is employed for enhancing the capacity of data transmission in wireless communication systems with various transmit antenna. In this paper, the performance of a space time block code (STBC), which is one type of STCs, is analyzed and simulated for pulse position modulation-time hopping (PPM-TH) and pulse amplitude modulation-direct sequence (PAM-DS) ultra wide band (UWB) systems in indoor wireless environments. Indoor channel is modeled as IEEE UWB channel model.
