Descriptions

docsIf31CmUsOfdmaChanCyclicPrefix — Multiple manufacturers; see the original MIB MIB copies (LibreNMS/Observium Community)

Cyclic prefix is added in order to enable the receiver to overcome the effects of inter-symbol interference (ISI) and inter-carrier interference caused by microreflections in the channel. The cyclic prefix (in usec) is converted into samples using the sample rate of 102.4 Msamples/s. There are eleven values for the length of the CP and the choice depends on the delay spread of the channel; a longer delay spread requires a longer cyclic prefix.
