Vehicom LTE Link Level Simulator (The LTE link level simulator is a comprehensive simulation software used for algorithm development, performance evaluation and system validation associated with LTE systems. The simulator have Matlab and C versions. The C version simulator consists of optimized algorithms which can be easily transferred to DSP platform. All the functional blocks provide dynamic memory allocation for data blocks and easy settings of parameters offering advanced user flexibility to customized simulation. When compared to other LTE simulation tools such as Steepest Ascent LTE toolbox and IsWireless LTE PHY Lab, our software not only provides a friendly GUI with various settings, user defined input and output data, and open architecture to integrate user defined function blocks, but also integrates our proprietary high-speed channel models for vehicle applications and high-speed trains applications. The The key features of the LTE link level simulator are summarized as below: 1) fast simulation speed, 2) )
