Description
Summary:The technology trend is progressing towards the sharing of the same spectrum by 4G and 5G mobile. The co-existance of 5GeMBB and 4G MBB spectrum needs to be placed cognitively to avoid Self Interference and side by side improving spectral efficiency. Dynamic spectrum Sharing DSS is useful (CR). The coexistence of 4G LTE and 5G New Radio (NR) gives a great opportunity in the real world. During the coexistence of these two signals, there will be chance of Interference of the signal. As a result, the reliability of the signal will be reduced due to interference. So in order to reduce the interference of the signal, the frequency of 4G LTE is kept fixed and that of 5G NR should be variable. It has been realized that when the frequencies of 4G LTE and 5G NR are equal, similar or same approximation value, then there will be BER and FER. Hence in order to reduce BER or FER, the frequency of 5G NR should be changed and kept in such a situation where there will be no BER or FER. Analysis of BER and FER indicates the reliability of the signal.
