LTE LAB™ is a complete simulation suite including link-level (LTE PHY Lab) and system-level (LTE MAC Lab) LTE simulators running under MATLAB environment. LTE PHY Lab is a comprehensive implementation of the 3GPP Release 8, 9 and 10 E-UTRA physical layer. LTE MAC Lab truly reflects the dynamic behavior of a modeled radio access network focusing on Radio Resource Management features such as scheduling and link adaptation and including implementation of propagation and mobility models.
