Space-time coding method for ultra wideband transmission system, involves obtaining vectors from elements of matrix, where row of matrix corresponds to utilization of transmission channel and column corresponds to radiative element

摘要

The method involves coding an information symbol block pertaining to a modulation alphabet in a sequence of vectors, where components of vector modulate impulse time hopping ultra wideband (UWB) signal, in position for a radiative element (330-1) i.e. UWB antenna, of a UWB transmission system (300). The vectors are obtained from elements of a matrix, where a row of the matrix corresponds to the utilization of transmission channel and a column of the matrix corresponds to the radiative element. The matrix is defined at a modulation position permutation, close to the matrix's rows and columns. An independent claim is also included for an ultra wideband transmission system comprising a set of radiative elements.
