Abstract

In order to investigate the effect of switching the transmission modes on the rate of reception and transmission of useful information in the LTE-Advanced network, it is necessary to estimate in real time the degree of the contribution of the specified process to the overall degradation of the channel capacity at each instant of time. A key parameter affecting the maximum achievable data reception and transmission rate in a channel of a given width and at the maximum permissible transmitter power is the signal-to-noise ratio in the channel, therefore it is extremely important to estimate the noise contribution of the switching process. To do this, it is first necessary to understand what real noise contribution the measurement system makes, the obligatory element of which is the radio frequency spectrum analyzer. In order to solve this problem, the method of determining the noise factor of the spectrum analyzer in real test conditions is considered and analyzed in this article.

评估实时测量LTE-Advanced最大接收和传输速度的充分性

为了研究切换传输模式对LTE-Advanced网络中有用信息的接收和传输速率的影响，有必要实时估计指定过程在每个时刻对信道容量总体退化的贡献程度。在给定宽度的信道中，在最大允许的发射功率下，影响最大可实现的数据接收和传输速率的关键参数是信道中的信噪比，因此估计开关过程中的噪声贡献是极其重要的。要做到这一点，首先有必要了解测量系统产生的实际噪声贡献，其中必不可少的元件是无线电频谱分析仪。为了解决这一问题，本文对实际测试条件下频谱分析仪噪声系数的确定方法进行了研究和分析。
