Comparing BPSK, QPSK, 4PAM, 16QAM, 16PSK, 64QAM and 32PSK

by Krishna Sankar on July 8, 2008

I have written another article in DSPDesginLine.com. This article can be treated as the third post in the series aimed at understanding Shannon’s capacity equation. For the first two posts in the series are: 1. [...]

Bounds on Communication based on Shannon’s capacity

by Krishna Sankar on June 18, 2008

Spectral efficiency vs Bit to noise ratio

This is the second post in the series aimed at developing a better understanding of Shannon’s capacity equation. In this post let us discuss the bounds on communication given the signal power and bandwidth constraint. [...]

Understanding Shannon’s capacity equation

by Krishna Sankar on June 15, 2008

Voltage levels with noise

Let us try to understand the formula for Channel Capacity with an Average Power Limitation, described in Section 25 of the landmark paper A Mathematical Theory for Communication, by Mr. Claude Shannon. Further, the following [...]
