Question 2. (40 Points) Consider a BPSK modulation with 2 signals: 2 where ??(t) and ?1 (t) for t E 10, T,l form a set of orthonormal basis functions. Signals so(t) and si(t) are equiprobable. We suppose that the transmission channel introduces an additive white Gaussian noise n(t). Thus, the received signal is given by r(t) s(t)+n(t), where the additive white Gaussian noise has power spectral density No/2. toT Y-X+N rit) a(t)+n(t) Figure...

Two types of digital-to-analog modulation techniques are Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK). In ASK, two different amplitudes, and only two, represent the digital information. In FSK, only two different frequencies are used to represent the digital data. The Goal The goal of the design project is to design a Commsim circuit that will generate the following analog carrier based on a digital input stream: Output 2 0 -1 -2...
