Abstract:
1. A three-Dimensional (3D) interleaver for interleaving an input stream in an Orthogonal-Frequency-Division-Multiplexing (OFDM) based Multiple-Input-Multiple-Output (MIMO) system, the 3D interleaver configured to: receive an input bit stream A(k), k=0, 1, 2, . . . , N select two parameters N form a 3D structure, the 3D structure having N write each input bit A(k) to each cell of the 3D structure, position of each cell in the 3D structure being defined by three co-ordinates, x, y, and z, where 0≦x≦N interleave the input bit stream A(k), k=0, 1, 2, . . . , N output an interleaved bit stream B(j), j=0, 1, 2, . . . , N
