Space-Time Codes from Spectral Norm: A Fresh Look (1407.3995v1)
Published 15 Jul 2014 in cs.IT and math.IT
Abstract: Current research proposes a natural environment for the space-time codes and in this context it is obtained a new design criterion for space-time codes in multi-antenna communication channels. The objective of this criterion is to minimize the pairwise error probability of the maximum likelihood decoder, endowed with the matrix spectrum norm. The random matrix theory is used and an approximation function for the probability density function is obtained for the largest eigenvalue of a Wishart Matrix.
