What is SC-FDMA and how it works in LTE? One of the major drawbacks of an OFDMA system is, that the transformation of a complex symbol mapped sequence (e.g. BPSK, QPSK, etc.) onto a small set of subcarriers produces time sequences that have high PAPR (Peak-to-Average Power Ratio). PAPR is the ratio between the maximum … Read more
While the goals and design targets specified above may be aggressive, options have been approved for consideration in the design that when used properly, will lead to a more efficient network compared to the existing 3G network. Therefore, in the quest to produce the best network possible in a cost-effective manner while meeting the goal … Read more
Here I write in simple word on LTE KPI Measurement Methodology and its Acceptance Procedure. As it’s for only at network start up stage and now a day worldwide so many operator starts to launch LTE and so this is the way for them to check of KPI in LTE LTE KPI Measurement Methodology The … Read more
OFDM Fundamental OFDM was selected for the downlink because it can Improved spectral efficiency Reduce ISI effect by multipath Provide better Protection against frequency selective fading OFDM is a scheme that offers good resistance to multipath and is now widely recognized as the method of choice for mitigating multipath for broadband wireless. It can be … Read more
DL Cell Aggregate Throughput The DL Cell Aggregate throughput (Effective RLC Aggregate Throughput) is the sum of the throughputs to all the users in the cell at an instant in time. This is to be measured following Monte Carlo simulations only. Design KPI for DL Cell Aggregate Throughput: 10MHz Channel Bandwidth: 13.4 Mbps per cell … Read more
