The invention concerns a method which consists in estimating the discrete symbols (d?k¿¿p?) of transmitted signals forming part of the components of a vector D of size N from a vector Y of a received signal L digital samples capable of being broken down into Y=AD+Y¿N? where A is a matrix of size LxN previously determined from measurements of at least one transmission channel reply and Y¿N? represents a vector of L noise samples. To achieve this the method consists in determining a greater triangular matrix T of size NxN and a vector Z of size N such that the quadratic criteria ?TX-Z??2¿ and ?AX-Y??2¿ are minimal for the same vector X of size N and dividing the vector Z and the matrix T into …

Why it's free to use
- Filed March 22, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 22, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 22, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
