Diversity Analysis of Bit-Interleaved Coded Multiple Beamforming with Orthogonal Frequency Division Multiplexing

On "Bit-Interleaved Coded Multiple Beamforming"

The interleaver design criteria described in [1] should take into account all error patterns of interest. In [1], let S be the number of streams employed and let αs be the number of times the stream s isemployed with a corresponding channel bit equal to 1 in an error path. Then, the interleaverdesign criteria for single-carrier systems at the beginning of Section II of [1] should be as ...

Coded-orthogonal frequency division multiplexing in hybrid optical networks

Future Internet should be able to support a wide range of services containing large amount of multimedia over different network types at a high speed. The future optical networks will therefore be hybrid, composed of different single-mode fibre (SMF), multi-mode fibre (MMF) and free-space optical (FSO) links. In these networks, novel modulation and coding techniques are needed that are capable ...

Bit Error Rate Performance Enhancement of Orthogonal Frequency Division Multiplexing

Orthogonal Frequency Division Multiplexing (OFDM) is a bandwidth efficient signaling scheme for wide band digital communications. A general problem found in high speed communication is Inter-Symbol Interference (ISI). ISI occurs when a transmission interferes with itself and the receiver cannot decode the transmission correctly. Orthogonal frequency division multiplex (OFDM) modulation is being...

Orthogonal Frequency Division Multiplexing with Diversity for Future Wireless Systems

Interleaved Orthogonal Frequency Division Multiple Access with Variable Data Rates

Multicarrier transmission systems with a specific subcarrier allocation such as equidistantly interleaved OFDMA or Interleaved Frequency Division Multiple Access (IFDMA) are promising candidates for future mobile radio systems, because they provide many advantages such as high flexibility, good performance and low computational complexity. In this paper, a new method for accommodation of differ...
