When we talk about LTE RF Planning then the one question in mind is that what about MIMO gains. Here I write Different Gain in LTE like MIMO Gains and Gains which brought by multiple antenna technology and By MIMO Like Power Combine Gain, Array Gain, Space Diversity Gain, Interference reduction gain and Spatial multiplexing … 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
The concept of Interference Rejection Combining (IRC) is to regenerate the transmitted signal based on the estimated data from the previous receptions, emulate the distortion occurring from the multi-path channels and, finally subtract all regenerated interfering signals from the uplink received signals to obtain more reliable estimation of original users’ data. This feature utilizes the … Read more
The challenge to broadband wireless comes from the scarcity of radio-spectrum resources. Regulatory bodies around the world have allocated only a limited amount of spectrum for commercial use. The need to accommodate an ever-increasing number of users and offering bandwidth-rich applications using a limited spectrum challenges the system designer to continuously search for solutions that … Read more
Here I write not all but important List of EUTRAN Capacity Limiting Factors for LTE and its definition. Impact of Interference on Capacity Interference is always a main contributor to capacity degradation in 1G to 3G cellular network and LTE is no difference. Besides external interference, there is a strong relationship also between the number … Read more
