Description: 针对OFDM系统，分成链路级仿真和系统级仿真两个部分。为了降低系统级仿真的复杂度，采用链路级仿真的部分结果。-It contains mainly two parts, i.e. link-level simulator and system-level simulator.
Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation.
System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.
Link-level simulator support SISO, 1 by x MRC, 2 by 1 STBC/SFBC, 2 by 2 Alamouti, x by 1 Antenna selection, x by y antenna selection.
System-level simulator, currently support only SISO and 1 by 2 MRC.
To start with, go into the folder sys_link_simu, and excute the following commond from matlab:
sys_link_simu_func(a,b)
where a is the link ada

Description: ns STBC for purely time-selective channels by transforming the
time-selective channels into frequency-selective channels, and by
adjusting existing space–time code designs over frequency-selective
MIMO channels to collect joint space–Doppler gains over purely
time-selective MIMO channels. Further, [14] uses the ideas of [12] to
develop a space–time code that can achieve full space-delay-Doppler
diversity for any number of transmit–receive antennas. However, to
quantify the maximum Doppler diversity order [2], the above papers
rely on a parsimonious critically sampled complex-exponential basis
expansion model (CCE-BEM) for the underlying purely time-selective
or doubly-selective channels [16]. However, the CCE-BEM may have
a large modeling error under certain channel conditions
