Abstract
Coexistence of wireless devices is a better option when devices operate in 2.4/5 GHz unlicensed radio spectrum. In recent times, LTE and Wi-Fi are the most promising wireless technologies that coexist. Joint operation of LTE and Wi-Fi in the same license-exempt bands is a real possibility but it requires advanced intelligent techniques. When such devices coexist, they suffer from significant interference and leads to performance degradation. This paper focuses on quantifying the impact of interference on the performance metrics and implements a novel Channel Condition-Based Equipment (CCBE) to manage such interference. Results show that for a fixed SNR there is a reasonable reduction in BER when transmissions are allowed after estimating the behavior of the channel. The coexistence environment is deployed in MATLAB with the aid of WLAN and LTE toolboxes.
