ABSTRACT: Achievable rate (AR) is significant to
communications. As to multi-input multi-output (MIMO) digital transmissions
with finite alphabets inputs, which greatly improve the performance of
communications, it seems rather difficult to calculate accurate AR. Here we
propose an estimation of con-siderable accuracy and low complexity, based on
Euclidean measure matrix for given channel states and constellations. The main
contribution is explicit expression, non-constraints to MIMO schemes and
channel states and constellations, and controllable estimating gap. Numerical
results show that the proposition is able to achieve enough accurate AR
computation. In addition the estimating gap given by theoretical deduction is
well agreed.
