Our modern digital communication system has been continuously evolving and it demands higher data rate and system efficiency to support millions of individuals around the clock. Since the complexity of the system increases the challenges also increases in designing, testing and implementation of transmission network and user equipment.
Adjacent Channel Leakage Ratio in any RF communication devices are generally described as the unwanted frequency generated by second or third order intermodulation distortion of the devices which fall near to the transmitting frequency band. In modern digital communication, any power leakage from transmitting channel to the adjacent channel cause distortion in other neighboring channel’s transmission and which affects the system efficiency. In order to make sure the system works perfectly within the allowed limits, an ACLR measurement has to be performed with a reference transmit signal.
