we present a practical link adaptation
algorithm for MIMO-OFDM systems. The proposed solution is
based on sounding the channel periodically and choosing the
optimal mode that will maximize the throughput or energy
efficiency (EE) while satisfying the application’s quality of service
(QoS) requirements. In addition, we address practical problems
such as the computational complexity of the algorithm and
determination of sounding period by novel closed form solutions
and iterative algorithms. Realistic link level simulations confirm
that the proposed solution achieves significant improvement
over existing link adaptation algorithms when the aim is to
maximize the throughput, and provides orders of magnitude
gain in energy efficiency compared to poorly chosen fixed modes
when used for energy efficiency maximization purposes. The
resulting algorithms are implemented on a real time MIMOOFDM testbed, and we report on the experimental results.

FemLorentzFit
Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model shows the basic steps of defining a magnetic frill voltage generator for a dipole antenna, and it also compares the resulting antenna impedance with known results.

bisection
Step 1: Set i=1 FA=f(a)
Step 2: while i≤ No do step 3-6.
Step 3 set p=(a+b)/2 FP=f(p)
Step 4 if FP<TOL or (b-a)/2<TOL then OUTPUT(p) STOP.
Step 5 set i=i+1
Step 6 if FA.FP > 0 then set a=p FA=FP else set b=p.
Step 7 OUTPUT (‘Method failed after No iteration,No=’, No) STOP.
