Creates an FIR Gaussian pulse-shaping filter.
x = fir_gaussps(bst)
x = fir_gaussps(bst, n)
x = fir_gaussps(bst, n, of)Legacy name: gaussfir
3-dB bandwidth-symbol time product.
Number of symbol periods between the start and the peak.
Oversampling factor or the number of samples per symbol.
Coefficients of the Gaussian pulse-shaping filter. The length of x equals 2*n*of + 1.
The following equation represents the analog impulse response of the Gaussian pulse-shaping filter: h(t) = sqrt(pi)*exp(-(pi*t / B)^2) / B, where B is the 3-dB bandwidth of the baseband Gaussian pulse-shaping filter, which MathScript uses the following equation to compute: B = sqrt(log(2) / 2) / bst. After MathScript transforms the Gaussian pulse-shaping filter into a discrete signal, the following equation represents the signal: h(k) = sqrt(pi)*exp(-(pi*k / B)^2) / B, where k ranges from -n*of to n*of. You can use the Gaussian pulse-shaping filter to counter the effects of intersymbol interference (ISI).
x = fir_gaussps(0.13, 3, 5);
