Based on the paper: C. Studer, M. Wenk, A. Burg, and H. Blocskei: "Soft-Output Sphere
Decoding: Performance and Implementation Aspects", Asilomar 2006
R ... is an upper triangular matrix obtained from the QR decomposition of the MIMO channel H
s ... received symbol (column) vector, s=Q^H*y
dist_ZF ... Distance for the zero forcing solution
symbols_ZF ... ZF solution
M ... number of bits encoded in every layer [1 x nTA]
symbol_alphabet ... for the demapping [nTA x 2^max(M)], filled with zeros for smaller symbol alphabets
bittable ... matrix containing the bits according to the symbol_alphabet [sum(M) x 2^max(M)])

lrvar
This code performs likelihood ratio test (LRT) for VAR model to determine optimal lag length,
constant term is automatically included.
Test is performed on contiguous lags, thus DOF=neqn^2*1. Guido Travaglini, 06.15.2011
