| Description: | Specifies the oversampling factor to be used to analyze OFDM signals. The oversampling factor determines the size of FFT that is used to convert time-domain samples of each OFDM symbol to corresponding frequency-domain values. If you set this attribute to a value greater than or equal to 1, the toolkit resamples the acquired signal to a value equal to the specified channel bandwidth times the oversampling factor. You must set this attribute to -1 to analyze at the sample rates indicated by the NIWLANA_RECOMMENDED_IQ_SAMPLING_RATE attribute. Note:You must set this attribute to -1 to avoid aliasing effects while analyzing a 160 MHz 802.11ac or 802.11ax signal as a signal with two segments, each having a bandwidth of 80 MHz. The default value is 1. Valid values are -1 and 1 to 10, inclusive. Get Function: niWLANA_GetOFDMDemodOversamplingFactor Set Function: niWLANA_SetOFDMDemodOversamplingFactor |
