In-Band On-Channe (IBOC) digital audio broadcasting (DAB) is a method of digital audio radio , which could transmit analog FM and digital audio simultaneously. However, due to the existence of fading and interference in FM bands, transmit capacity has reached its limitations for the bandwidth, thus, adding digital transmission in the crowded FM band is a challenging proposition. Diversity is one of...
Under limited channel capacity condition, this study investigates a combined source and channel coding algorithm providing a uniform video transmission rate to achieve better system performance in wireless MIMO systems. In the proposed algorithm, we applied MPEG2 video source coding scheme with convolutional channel coding as well as space-time block coding techniques, associated with BPSK/QPSK modulation...
Broadband wireless access (BWA) technique has attracted great attention in the last mile access industry. In this paper, an effective MAP receiver for concatenated space time block code (STBC) and convolutional code MIMO-OFDM system (denoted as CSCM receiver) for further performance improvement of IEEE wireless MAN-OFDMA system is derived and designed in detail. Simulation results show that the receiver...
