In this paper, real-time video transmission with quality of service (QoS) assurance over orthogonal frequency division multiplexing (OFDM) wireless systems is studied. Three quasi-optimal subcarrier allocation schemes, namely regular, delay tolerant and adaptive, are proposed. In the proposed schemes, effective throughput per subcarrier employing adaptive forward error correction (FEC) coding in a...
In this paper a power and rate adaptation algorithm for a MC-CDMA system with different quality of service (QoS) requirements is proposed. We consider the forward transmission case where different classes of data are simultaneously transmitted for different active users. The system allocates different data streams over different subchannels or blocks according to the each user's CSI, and assigns to...
