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 the quality of received signal through diversity combining. Adaptive modulation with combining will make higher-order transmission mode feasible under the same required BER and enhances spectral efficiency.
