Abstract :
We propose the construction and the decoding of noncoherent space-time codes which use all the complex degrees of freedom of the system (M×(1-M/T)). They extend the construction of codes for differential reception for which the number of real degrees of freedom per channel use is M. They are derived from codes on the Grassmann manifold G(T, M) where T is the code length and M is the number of transmit antennas.
