— Multi-antenna communication systems have the potential to play an important role in the design of the next generation broadband wireless communication systems. In this paper, we study a single-user multi-antenna system with perfect channel state information (CSI) both at the transmitter and the receiver. Beamforming is used to exploit the perfect channel… (More)
In this paper, we investigate the performance of bit interleaved coded multiple beamforming (BICMB). We provide interleaver design criteria such that BICMB achieves full spatial multiplexing of min(N, M) and full spatial diversity of N M with N transmit and M receive antennas over quasi-static Rayleigh flat fading channels. If the channel is frequency… (More)
It is well-known that using multiple antennas provides a substantial capacity and diversity increase for wireless communication systems. A multi-input multi-output (MIMO) technique that utilizes the channel knowledge both at the transmitter and the receiver is known as beamforming. Beamforming separates a MIMO channel into parallel subchannels. It was… (More)
A MIMO system equipped with a new class of antenna arrays, henceforth referred to as multifunction reconfigurable antenna arrays (MRAAs), is investigated. The elements of MRAA, i.e. MRAs presented in this work are capable of dynamically changing the sense of polarization of the radiated field thereby providing two reconfigurable modes of operation, i.e.… (More)
— In this paper we will show and quantify both analytically and via simulations that the use of channel knowledge at the transmitter, the technique known as beamforming, achieves the maximum diversity in space when the best eigenmode is used (single beamforming). Furthermore, we will investigate beamforming in conjunction with next generation wireless local… (More)
This paper addresses the performance of bit-interleaved coded multiple beamforming (BICMB) ,  with imperfect knowledge of beamforming vectors. Most studies for limited-rate channel state information at the transmitter (CSIT) assume that the precoding matrix has an invariance property under an arbitrary unitary transform. In BICMB, this property does… (More)
— In this paper, we analyze the performance of bit interleaved coded multiple beamforming (BICMB).
In this paper we analyze single beamforming in combination with bit interleaved coded modulation (BICM) and OFDM. We show that BICM-beamforming-OFDM (BBO) achieves full diversity in space and frequency independent of the power delay profile of the channel. Since only one stream of data is transmitted over all transmit antennas, a simple interleaver is shown… (More)
