Adaptive modulation and coding is a commonly used technique to improve throughput in wireless system. Due to the delay in channel condition feedbacks, the actual channel condition may change at the time of transmission and results in capacity loss. In this paper, we establish a model to analyze the capacity loss due to channel condition feedback delay. Simulation results show that our approach is...
Adaptive modulation and coding schemes (MCS) are key components in the next generation wireless system to improve channel throughput by adaptively choosing the MCS according to channel states. However, due to channel feedback delay, processing delay, and scheduling delay, the channel state may change at the time of transmission and results in channel capacity loss. Simply using previous channel state...
