How do you calculate spectral efficiency in LTE?

For example, a system uses channel bandwidth as 2 MHz and it can support a raw data rate of say 15 Mbps, assuming 2 Mbps as overhead then net date rate will be as 13 Mpbs, then its spectrum efficient can be calculated as follows: Spectral efficiency= 13 x 10^6 / 2 x 10^6 = 6.5 bits/second/Hz.

What is spectral efficiency formula?

Example 1: A transmission technique using one kilohertz of bandwidth to transmit 1,000 bits per second has a modulation efficiency of 1 (bit/s)/Hz. … The spectral efficiency or modulation efficiency is 56,000/3,100 = 18.1 (bit/s)/Hz downstream, and 48,000/3,100 = 15.5 (bit/s)/Hz upstream.

What is LTE spectral efficiency?

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. … Normalized uplink throughput with an AMC in LTE.

What is spectrum efficiency of a cellular network?

Also known as spectral efficiency or bandwidth efficiency, a cellular network’s spectral efficiency is equivalent to the maximum number of bits of data that can be transmitted to a specified number of users per second while maintaining an acceptable quality of service.

What is 5G spectral efficiency?

5G New Radio is capable of providing a downlink throughput 2.31 Gbps and uplink throughput of 2.47 Gbps with certain configuration shown below assuming 100 MHz channel bandwidth. ( Single carrier component) Downlink Spectral Efficiency = 2.31 x 10^9 bps / 100 x 10^6 Hz = 23 bits/second/Hz.

Which bandwidth is more efficient?

Explanation: Of all the modulation showed, QAM is the most bandwidth efficient one. Explanation: The primary communication resources are transmitted power and channel bandwidth. 8. Greater the redundancy lesser is the bandwidth expansion.

What is the average uploading speed of 4G LTE network?

What is the average uploading speed of 4G LTE network? Explanation: Verizon 4G LTE wireless broadband is 10 times faster than 3G able to handle download speeds between 5 and 12 Mbps (Megabits per second) and upload speeds between 2 and 5 Mbps. 6.

What is the condition of handoff?

Explanation: Handoff occurs when a mobile moves into a different cell while a conversation is in progress. The MSC automatically transfers the call to a new channel belonging to the new base station.

Why the shape of cell is not circle?

Why the shape of cell is not circle? Explanation: Circle is the first natural choice to represent the coverage area of a base station. But while adopting this shape, adjacent cells cannot be overlaid upon a map without leaving gaps or creating overlapping regions. 8.

What are the advantages of frequency reuse?

Frequency Reuse

  • Allows communications within cell on a given frequency.
  • Limits escaping power to adjacent cells.
  • Allows re-use of frequencies in nearby cells.
  • Uses same frequency for multiple conversations.
  • 10 to 50 frequencies per cell.
