Abstract :
In this paper, the problem of constellation and rate selection in adaptive modulation and coding according to the channel condition is considered. A new selecting rule based on the finite blocklength analysis of channel capacity is proposed. When applied to the LTE system, the proposed selecting rule reveals interesting, new combinations of constellation and rate which yield significantly better performance in comparison with corresponding combinations suggested in the LTE system.
