Specifies the length of the triangular-weighted moving window across subcarriers that is used for averaging the channel estimate.

This property is used only when you set the OFDMModAcc Ch Estimation Interpolation Type property to Triangular Smoothing. The window is always symmetrical about the subcarrier. The length of the window is reduced at the edges in order to keep it symmetrical. For a window length of L, the weights generated are 1, 2, 3, ..., (L+1)/2, ..., 3, 2, 1. For a fully occupied channel bandwidth, valid values are all odd numbers between 1 and half the number of subcarriers in the bandwidth, inclusive. For 802.11ax MU and TB PPDU signals, 802.11be MU and TB PPDU signals, and 802.11bn MU and TB PPDU signals, the valid values are all odd numbers between 1 and the size of the smallest RU.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is 5.
