This paper, mainly, aims to present a full diversity scheme in the presence of a quasi-static Rayleigh fading channel and an MRC combiner in the receiver. This scheme is based on the fact that transmitted signal will be divided on several transmit antennas. Such scheme reduces the transmission time and increase the data rate. We will present a generic BER equation for this scheme and illustrate our...
This paper present the results and performance of angle diversity for direction of arrival (DOA) setup. The 4times4 Butler matrix was been used at transmitter and receiver sides. The 2times2 rectangular patches have been used as a transmitter and receiver medium for wireless transmission. The operating frequency for this measurement is 2.4 GHz in WLAN application. This paper analyze about DOA and...
Polarization diversity is an interesting alternative to space diversity, but the channel characteristics need to be investigated. To evaluate the dual polarized channels, a 2times2 multiple-input-multiple-output (MIMO) wireless testbed has been developed. In addition, a dual polarized microstrip patch antenna array has been designed to be used as the transmitter and receiver in this system. Performance...
In this paper a technique is presented on how to enhance the received signals in a near field multi-input multi-output (MIMO) environment where beam forming is not possible. This is done through the use of adaptivity on transmit. Polarization diversity can also be implemented. This technique is based on the principle of reciprocity, is independent of the material medium in which it is transmitting,...
