Energy of Transmit Pulses in Digital Communication
You must have made a mistake in your calculations. Both waveforms have the same energy. (I disagree with @Marcus' answer).
Let's say the pulse is $p(t)$ and it has energy $E$. Then, the energy of $p(t)...

Energy of Transmit Pulses in Digital Communication
How do we reconcile with the fact that the transmit bit energy (energy per pulse) is constant.
We don't – it isn't constant, as you've shown! (Note that you're also making a bit of a mistake there: ...

Mapping PAM-17 levels to PAM-5 levels
Quantizing a 17-level signal to 4 levels loses information. Oversampling will not help you recover it, since the information content of 1 is the same as that of <...

Mapping PAM-17 levels to PAM-5 levels
The mapping scheme should be such that output of the filter remains same for the case when directly 17-level signals are passed through FIR filter and when 17-level signals are first mapped to 4 level ...

How to derive the error probability for pulse position modulation in digital communication?
2-PPM is an orthogonal modulation scheme just like 2-FSK (i.e. BFSK), and the same BER equation applies to both which is:
BER = 0.5 * exp(-(Eb/N0)/2).
I hope this still helps -- it's been a while ...
