OSNR Margin (Optical Signal-to-Noise Ratio Margin) is a critical parameter in optical communication systems that measures the difference between the actual OSNR and the minimum OSNR required for error free signal detection (typically defined by a bit error rate threshold). It provides insight into how much "headroom" or tolerance a system has before it fails to maintain acceptable performance.

Higher OSNR Margin means the system is more resilient to degradation over time or due to network changes.

 LTE key feature (ICIC)


Inter-cell interference cancellation (ICIC) is a technique that aims to reduce the interference caused by neighboring cells in a cellular network, especially at the cell edge where the signal quality is often poor. ICIC can improve the performance and throughput of LTE users by allowing them to share the same frequency and time slot with other cells, or by coordinating the transmission and reception of signals among different cells.

There are different types of ICIC schemes, such as static frequency reuse, dynamic frequency reuse, cell-coordinated schemes, and inter-cell co-operative schemes.

Each scheme has its own advantages and disadvantages in terms of complexity, applicability, and performance. Some of the factors that affect the ICIC scheme are the number of cells in the network, the number of users per cell, the channel conditions, and the interference level.
