The authors have extended the calculations with a 3GPP LTE specified spatial correlation model in order to get realistic performance results and a usable tool in a realistic standardized mobile system. In addition, the bit error rate calculation method has been completed by a stochastic interference model, which influences the received interference energy by several different parameters, which will be assumed as random variables in this work. The interference model can be considered flexible in the sense that different random distributions can be defined for the implied parameters. In this work, the authors provide analytic bit error rate calculation results applying the mentioned stochastic interference model according to a frequency hopping scenario.}, year = {2015}, pages = {309-317} } @mastersthesis{MTMT:2944056, title = {Modeling and Radio Resource Management of Advanced Wireless Networks - Korszerű vezeték nélküli hálózatok modellezése és erőforráskezelése}, url = {https://m2.mtmt.hu/api/publication/2944056}, author = {Mráz, János Albert}, unique-id = {2944056}, year = {2013} } @book{MTMT:2694225, title = {Modeling and Optimization of Advanced Wireless Networks}, url = {https://m2.mtmt.hu/api/publication/2694225}, isbn = {9783659436765}, author = {Mráz, János Albert}, publisher = {LAP}, unique-id = {2694225}, year = {2013} } @article{MTMT:2685827, title = {General interference analysis of M-QAM and M-PSK wireless communications}, url = {https://m2.mtmt.hu/api/publication/2685827}, author = {Mráz, János Albert and Pap, László}, doi = {10.1007/s11276-012-0469-5}, journal-iso = {WIREL NETW}, journal = {WIRELESS NETWORKS}, volume = {19}, unique-id = {2685827}, issn = {1022-0038}, abstract = {This work includes an accurate and general technique, which has been developed to analyze the SER of coherent M-QAM and PSK schemes for various conditions of the transmission.
