Description
This page on LTE bandwidth vs sampling frequency vs resource block covers relation between LTE bandwidth,sampling frequency and resource block. Please check table below for values. For example 512 point FFT case,bandwidth is 5MHz, sampling frequency is 7.68MHz and number of resource blocks are 25. Please check our page on LTE Terminology for description of these terms.
关于LTE带宽与采样频率与资源块的本页,涵盖LTE带宽、采样频率和资源块之间的关系。请检查下表的值。例如 512 点 FFT 情况下,带宽为 5MHz,采样频率为 7.68MHz,资源块数为 25。请查看 LTE 术语页面,了解这些术语的说明。
