Note: In earlier versions of the 802.11 standard, the (BCC) OFDM example was given in Annex G. However, an error existed (e.g. in IEEE Std 802.11-2007) in that the FCS was incorrect (see link or search online for "IEEE 802.11-09/0042r0").
The WiFi (802.11) standards documents are free to...
In Part I of this blog, we saw that we can construct two partially correlated signals, x1(t) and x2(t), as:
\[
\; \; \; \; \; \; \; \; \;\; \;\; \; x_1(t) = \sqrt{P_1}s_1(t) \\
\; \; \; \; \; \; \; \; \;\; \;\; \; x_2(t) = \sqrt{P_2}ρ∗s1(t)+√(1−|ρ|2)s2(t)ρ∗s1(t)+(1−|ρ|2)s2(t)
\]
where P1 and...

Introduction
It is often useful to be able to generate (real or complex-valued) signals with specific cross-correlations. In the simplest...
I was recently asked how to estimate the frequency of a noisy sine wave over a short capture. In this context, 'short' means the total capture duration relative to the period of the sine wave. So we may have, at most, a few periods of the sine wave (or, at worst, less than one period). Here is...
We often plot some data on a graph and wonder if there might be a simple mathematical function to describe what we see:
In many cases, a polynomial approximation would be particularly useful. That is, we want to describe the line in the form...
Introduction
I didn't want to buy an expensive variable power supply for my small, low-power projects, so decided to make my own. I couldn't find much inspiration online, so I thought I'd write up my design in detail here in case it helps anyone else. Circuit schematics, layout, source code...
