Pulse Shaping Filter

From the previous articles, we have seen how a Tx generates a signal from the numbers and the Rx recovers

$Spectral efficiency R_b/B versus E_b/N_0 determines the overall merit of a modulation scheme. This figure is drawn for BER = 10^{-5} and a Square-Root Raised Cosine pulse with 50% excess bandwidth$

Computing Error Rates

Having built a simple digital communication system, it is necessary to know how to measure its performance. As the names
