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 2000s. As the signals sent from different transmit antennas interfere with one another, processing is required at both the transmitter and the receiver in order … Read more
Here I write about each and every channel of LTE with its Functionality. How many channel and what its work. LTE Channel Functionality. List of channel with its work Physical channels PDSCH: Physical Downlink Shared Channel PBCH: Physical broadcast channel PMCH: Physical multicast channel PDCCH: Physical Downlink Control Channel PCFICH: Physical control format indicator channel … Read more
It is very important when we talk about LTE Planning frequency band selection and Cyclic Prefix planning here I write basic background of it. Frequency Band Selection As many Operators worldwide possess spectrum in various frequency bands, choosing which band to use for LTE is always an important consideration. Parameters that will affect the overall … Read more
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 the direction of the receiver and away from interference, thereby improving the received SINR. The beam-forming weight vector should increase the antenna gain in the … Read more
Spatial multiplexing is where multiple independent streams are transmitted across multiple antennas. If the receiver also has multiple antennas, the streams can be separated out using spatial multiplexing. Instead of increasing diversity, multiple antennas in this case are used to increase the data rate or capacity of the system. In a rich multipath environment, the … Read more
Here I just review how TTI Bundling for LTE link budget first lets see what link budget feature overview. Features Overview Below is a quick summary of specific features and their corresponding impact on the radio network link budget result if the features or functionalities are deployed. TTI Bundling By repeating the same uplink information, … Read more
