One of the aims of the CDMA1X system is to maximize the number of its users. If each mobile station (MS) adjusts its transmitter power to minimize the signal noise received by the base transceiver station (BTS), the capacity of the system is maximized. Higher power brings higher interference and results in more capacity loss. Power control can adjust the transmission power of the MS and BTS, aiming to minimize the interference
After learning this course, you will learn the following：

Data configuration of the power control
Chapter 1 Goals and Principles of Power Control
Chapter 2 Categories and Arithmetic of Power Control
Chapter 3 Data Configuration of Power Control
Each couple of customers is in a same room.
Each couple of customers speaks a language different from that spoken by other couples.
If the noise becomes louder, all the customers will raise their voices.
If the noise is too louder, the customers may go to other rooms.
The customer who speaks too loudly will affect the communication of others.
The transmission power of the control BTS and MS must ensure that the signal sent to the receiver through the complicated radio space can meet the threshold of correct demodulation.
When the first principle is satisfied, the transmission power of the BTS and MS is required to be lowered as much as possible to decrease the interference between users and best optimize the network performance.
The transmission power of the MS near the BTS is lower than that of the MS far from the BTS and of the MS in the fading areas.
