We apply coset codes to adaptive modulation in fading channels. Adaptive modulation is a powerful technique to improve the energy efficiency and increase the data rate over a fading channel. Coset codes are a natural choice to use with adaptive modulation since the channel coding and modulation designs are separable. Therefore, trellis and lattice codes designed for additive white Gaussian nois...

Adaptive modulation and diversity combining represents the enabling techniques for the future generation of wireless communication. Adaptive modulation is a transmission scheme in digital communications where the transmitter adapts its transmission mode in accordance with the channel. In TDD systems the channel state is known in the transmitter side because of channel reciprocity, hence the ada...

This paper surveys the various combining schemes along with adaptive coded modulation with respect to fading in wireless environment. Adaptive coded modulation increases the energy efficiency and data rate and this modulation scheme along with combining provides high spectral and power efficiency. Antenna diversity systems can increase the reliability of wireless fading channels by improving th...
