What are orthogonal signals?
Orthogonal signals are used extensively in the communications industry. They range from a simple sine/cosine quadrature signals to multiple signals whose inner product is equal to zero. Orthogonal signals can be used for several different applications.
What are antipodal signals?
If the pulse shapes are identical and the pulses have opposite polarity, as in this. example, the resulting signal set is referred to as an antipodal signal sets. In other words, a signal set. s0(t),s1(t) is an antipodal signal set and the two signals are said to be antipodal if s1(t) = −s0(t) for all t.
