A digital transmission system employs the waveforms
where hTx(t) is a rectangular pulse of unit amplitude and duration
The channel noise is AWGN with PSD  Determine:
a) An orthonormal basis for the waveform set, the corresponding constellation and decision regions.
b) An upper bound to the error probability by using the minimum distance between constellation points.
