A random matrix approach to the finite blocklength regime of MIMO fading channels [PDF]

2012 IEEE International Symposium on Information Theory Proceedings, 2012
This paper provides a novel central limit theorem (CLT) for the information density of the MIMO Rayleigh fading channel under white Gaussian inputs, when the data blocklength n and the number of transmit and receive antennas K and N , respectively, are large but of similar order of magnitude.

Block Error Rate Minimization of Downlink MIMO‐NOMA With Finite Blocklength

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper investigates the downlink multiple‐input multiple‐output (MIMO)‐non‐orthogonal multiple access (NOMA) transmission with finite blocklength (FBL). Our aim is to achieve the minimum average block error rate (BLER) by proposing an efficient power, rate, and blocklength allocation scheme.
