A NOVEL BLIND ESTIMATION ALGORITHM

In this paper, we propose a cumulant-based blind signal estimation alg orithm for estimating the channel matrix in an n-sensor m-source syste m, The only available information is the output of the n sensors, The algorithm first deduces the number of sources, which may be greater th an or equal to the number of sensors, from the output cumulant matrix, Then, by suitably arranging the elements within that matrix, the entr ies of the original channel matrix are estimated row by row, Simulatio ns results are given to illustrate the performance of the algorithm.
