Adaptive modulation techniques for duplex OFDM transmission

The design tradeoffs of turbo-coded burst-by-burst adaptive orthogonal frequency division multiplex (OFDM) wideband transceivers are analyzed. We demonstrate that upon aiming for a higher throughput a higher proportion of low-quality OFDM subcarriers has to be used for the transmission of inherently vulnerable high-order modem modes, transmitting several bits per subcarrier. Upon invoking turbo...

Adaptive Modulation for OFDM Systems

The goal for the fourth generation (4G) of mobile communications system is to seamlessly integrate a wide variety of communication services such as high speed data, video and multimedia traffic as well as voice signals. One of the promising approaches to 4G is adaptive OFDM (AOFDM). In AOFDM, adaptive transmission scheme is employed according to channel fading condition with OFDM to improve the...

Adaptive OFDM Modulation Used For SDR

Software defined radio (SDR) is the future trend for mobile communication. A SDR is supposed to facilitate high speed multimedia application for future mobile standards. Adaptive modulation forms an integral part of SDR system with robust and high data rate capability. Here we have analyzed adaptive modulation scheme with their performance in changing channel condition. The modulation scheme st...

Adaptive Modulation and Interleaving for BICM-OFDM

The optimisation of communication systems with respect to the applied channel code is a more recent topic in the field of adaptive communications compared to the optimisation of uncoded transmissions. Besides the information theoretical statements the applied codes are not perfect but practical codes which poses the additional problem to capture the structure and overall behaviour of a code suf...
