Object
column number of samplesUsOfdmaRollOffPeriod
Windowing is applied in order to maximize channel capacity by sharpening the edges of the spectrum of the OFDMA signal. Windowing is applied in the time domain by tapering (or rolling off) the edges using a raised cosine function. There are eight possible values of roll-off prefix. The Roll-Off Period is given in us and in number of samples using the sample rate of 102.4 Msamples/s. The configuration where Roll-off prefix value is greater than or equal to cyclic prefix value is considered invalid.
