1 RB sensitivity at middle RBs poor than other RBsPei-Che Chang
?
1. Measuring LTE sensitivity with a single resource block (RB) located in the middle of the channel can degrade sensitivity. This is because control channels like the primary synchronization signal (PSS), secondary synchronization signal (SSS) and physical broadcast channel (PBCH) are also located in the middle, making decoding more difficult.
2. With a single middle RB, the coding rate needs to be twice as high on subframe 0 compared to other subframes to achieve the same block error rate. This requires at least 3dB higher signal-to-noise ratio (SNR).
3. Testing sensitivity with few RBs near the channel center can also degrade sensitivity slightly due to interference from the in-band

Li-Fi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. It is a faster and more secure alternative to Wi-Fi networks. Li-Fi works by transmitting data through LED light bulbs and receiving data through photodetectors. At its core, Li-Fi uses visible light communication (VLC) technology which utilizes part of the optical spectrum that is not used for illumination for high-speed data communication. Li-Fi has several advantages over Wi-Fi such as higher speed, more secure communication, and the ability to work in places where radio waves are not allowed or may interfere with sensitive equipment. However, Li-Fi also faces challenges as it requires line

Wavelet analysis involves representing a signal as a sum of wavelet functions of varying location and scale. Wavelet transforms allow for efficient video compression by removing spatial and temporal redundancies. Without compression, transmitting uncompressed video would require huge storage and bandwidth. Using wavelet compression, a day of video could be stored using the same space as an uncompressed minute. The discrete wavelet transform decomposes a signal into different frequency subbands, making it suitable for scalable and tolerant video compression standards like JPEG2000. Wavelet compression provides better quality at low bit rates compared to DCT techniques like JPEG.
