Question

example 7.1 question EXAMPLE 7.1
Consider the signals s1(t), s2(t), s3(t), and s4(t) shown in Figure 7.3. Using the Gram-Schmidt orthogonalization procedure, determine a set of orthonormal basis functions.

Using the waveforms derived and shown in Example 7.1:
a) Sketch the simplified block diagram of the transmitter and receiver as shown in figure 7.2
b) Estimate the receive voltages for each transmit signal and for each branch in the receiver.
