| Abstract: | Implicit training(IT)algorithm can achieve multiple packet reception of complex data for Ad hoc networks.In this paper,an improved algorithm using the nature of Hilbert transform as well as the cyclostationarity of implicit training sequences is proposed,which can achieve the separation of 2-D analytic signals.We studied the performance of this new algorithm and factors affecting it through simulation.Compared with the original algorithm,the proposed algorithm can effectively improve the capability of multi... |
