# Daily Report 4 :::success ### Task 4 ## 22nd of July 2021 :::info **IVC 5G O-RAN Summary** Physical Channel Constraints on what kinds of signal can be transmitted Data rate limits => maximum data rate - Signal Power - Noise Power - Distortion Without distortion or noise, R will have ꝏ value and the power of error (Pe) approach to 0. Gaussian Noise Formula : C= 1/2 B Log ( 1+SNR ) Signal => Continous, Discrete, Complex, Real Signal’s Characteristic 1. Power 2. Bandwith ![](https://imgur.com/A5yGtAP.png) :::spoiler Whats’s noise ? Any unwanted component of signal a. Internal/ Thermal Noise => Additive (White Gaussian) b. Distortions c. External Interface ![](https://imgur.com/e4E37Rk.png)
