用BP网络完成函数的逼近 P网络通常有一个或多个隐层，隐层中的神经元均采用sigmoid型变换函数，输出层的神经元采用纯线性变换函数。本例应用一个两层BP网络来完成函数逼近的任务，其中隐层的神经元个数是5。(network to be completed by BP function approximation P networks usually have one or more hidden layer, a hidden layer neurons are used sigmoid-type transformation function, the output layer neurons using pure linear transformation function. The application of a two-tier cases BP network function approximation to complete the task, hidden layer neuron number is 5.)

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.
