Spread spectrum orthogonalization of superimposed training signals in OFDM systems

Descripción del Articulo

In this paper, we propose a novel Superimposed Training (ST) technique for Orthogonal Frequency Division Multiplexing (OFDM) systems, where data and training signals are divided in orthogonal code domains in order to mitigate the interference between them. The data signal is partitioned into disjoin...
