MIMO+OFDM Simulation Under LTE Standards

When conducting MIMO+OFDM simulations under LTE standards, utilizing a complete simulation program is essential. This program incorporates various parameters and variables such as antenna configuration, carrier frequency, and modulation schemes to cover diverse operational scenarios. The implementation includes configurable modules for key system parameters through structure arrays or parameter files, allowing flexible scenario testing. Furthermore, the simulation accounts for different wireless channel models including AWGN, Rayleigh, and Rician fading channels through dedicated channel modeling functions. The program typically implements channel estimation algorithms like LS or MMSE, and MIMO detection techniques such as ZF or MLD for signal recovery. Such comprehensive simulation architecture ensures accurate and reliable results by incorporating realistic LTE physical layer processing chains with appropriate cyclic prefix insertion, FFT/IFFT operations, and pilot symbol arrangement.
