How Open-Loop Transmit Diversity in Wimax?

Transmit spatial diversity is a newer phenomenon than receive diversity and has become widely implemented only in the early 2000s. Because the signals sent from different transmit antennas interfere with…

CDMA Spatial Diversity

Diversity Reception: Multiple Antennas at Base Station Each Antenna is Affected by Multipath Differently Due to Their Different Location Allows Selection of the Signal Least Affected by Multipath Fading If…

Spatial Multiplexing and Receiver Gains in Wimax

Spatial Multiplexing In a multipath environment, the data rate increase due to MIMO is equal to the number of MIMO antennas. Rather than to transmit the same bit of more…

Types of Diversity Space, Time, Spatial, Frequency and Polarization

We know that we normally have several independent paths from TX to Rx of different lengths, these are affected and delayed differently, Signals that start out together at the transmitter…

Advanced Antenna Systems,Transmit diversity and Beamforming in Wimax

Advanced Antenna Systems The WiMAX standard provides extensive support for implementing advanced¬† multiantenna solutions to improve system performance. Significant gains in overall system capacity and spectral efficiency can be achieved…
