How can efficiency of a spectrum be improved?
The spectral efficiency can be improved by radio resource management techniques such as efficient fixed or dynamic channel allocation, power control, link adaptation and diversity schemes. A combined fairness measure and system spectral efficiency measure is the fairly shared spectral efficiency.
What is spectral efficiency in LTE?
The spectral efficiency is generally defined by the transmission data rates divided by the channel bandwidth and expressed in bits per second, per Hz (bps/Hz). It is also called as normalized throughput. There are two primary factors that dominate the spectral efficiency: MCS (modulation and coding scheme) and SINR.
How can we improve throughput in LTE?
One thing that can really help in increasing the throughput is the optimum mobility strategy. Consider two LTE layers, for instance L800 and L1800 with same bandwidth. In this case, L800 will have a higher coverage as it is a lower frequency. So, the user count on L800 will be higher compared to L1800.
What is excellent spectral efficiency?
Spectral efficiency is typically referred to as bits per second per hertz (bps/Hz). A spectral efficiency of 30 bps/Hz is considered a very high number and one of the many highlights of G1. Without high spectral efficiency, even the most groundbreaking technology will be less useful.
