Spatial multiplexing and Receive Diversity in Wimax

Spatial multiplexing and Receive Diversity in Wimax Spatial multiplexing WiMAX also supports spatial multiplexing, where multiple independent streams are transmitted across multiple antennas. If the receiver also has multiple antennas,…

What is Basic behind MIMO for LTE

What is Basic behind MIMO for LTE MIMO and other transmit spatial diversity scheme is a newer application than receive diversity and has become widely implemented only in the early…

What is AMC & its Algorithm in LTE

The effective Eb/No and hence the spectral efficiency depend on BLER. However there are QoS requirements which also have to be considered. Taking both into account leads to a target…

List of LTE Equipment Related Parameters

LTE parameters Equipment related parameters include the base station, antenna, and terminal. The link budget parameters vary with the base stations, antennas, and terminals of different vendors. These parameters affect the…

Modulation Techniques in LTE

LTE devices use several modulation techniques to modulate data and control information. These modulation techniques include: QPSK (2 bits per symbol), 16QAM (4 bits per symbol), and 64QAM (6 bits…

Visualization of Beam Forming in LTE

Currently, beam forming is only applicable for TDD version of LTE. The time synchronous version of LTE TDD on uplink and downlink also makes the implementation of beam forming more…

Interference Limited MIMO Systems for Wimax

The third assumption—that the background noise is Gaussian and uncorrelated with the transmissions—is especially suspect in a cellular MIMO system. All well-designed cellular systems are by nature interference limited: If they…

Beam Forming background for LTE

Multiple antennas in LTE may also be used to transmit the same signal appropriately weighted for each antenna element such that the effect is to focus the transmitted beam in…
