Relation between Signal to Noise ratio and Logical Interference

Click For Summary
SUMMARY

The discussion focuses on the relationship between Signal to Noise Ratio (SNR) and logical interference, particularly in the context of modifying equations for SNR to account for logical interference. Key insights include the importance of understanding the types of interference, such as thermal noise and interference from other cells or base stations. The discussion references the concept of E_c/I_0 and its variations, emphasizing that the interpretation of interference can vary based on the specific technology or standard being used.

PREREQUISITES
  • Understanding of Signal to Noise Ratio (SNR) and Signal to Interference plus Noise Ratio (SINR)
  • Familiarity with telecommunications concepts such as E_c/I_0
  • Knowledge of different types of interference in communication systems
  • Basic grasp of telecommunications standards and technologies
NEXT STEPS
  • Research the variations of E_c/I_0, including E_c/I_{0r} and E_c/\hat I_{0r}
  • Explore the impact of thermal noise on SNR in communication systems
  • Study the effects of interference from multiple base stations on SINR
  • Investigate telecommunications standards that define interference metrics
USEFUL FOR

Telecommunications engineers, signal processing specialists, and researchers in wireless communication systems will benefit from this discussion, particularly those focused on optimizing SNR and understanding interference dynamics.

Hi there, I want to modify a equation which is written for Singal to Noise Ratio. Now I want to change for logical interference. But I could not find any reliable source of explanation, " what is the relation between SNR/SINR and interference(Logical/Physical)?"

It kind of depends on what type of system you're working with.

Here is a place to start.

That gives you an explanation of [itex]E_c/I_0[/itex]. But after that you want to consider whether the interference from other cells/base stations/NodeB/access points are also being considered as "interference." Then, you'll still need to consider whether the receiver's internal thermal noise is considered too. They all take different forms of "[itex]E_c/I_0[/itex]" such as [itex]E_c/I_{0r}[/itex], [itex]E_c/\hat I_{0r}[/itex]. Of course, even that notation depends on the standard/technology in question.
