Chirp css

WebWith the proliferation of Internet-of-Things (IoT), the chirp spread spectrum (CSS) technique is re-emerging for communications. Although CSS can offer high processing gain, its poor spectral efficiency and the lack of orthogonality among different chirps tend to limit its potential. In this paper, we derive the condition to orthogonally multiplex an arbitrary … WebChild support agencies can promote the Earned Income Tax Credit to eligible working parents. The IRS estimates 4 out of 5 eligible workers claim the EITC, averaging a little over $2,000 per refund, but millions of people still don’t take advantage of this credit. Use this IRS social media toolkit to help raise awareness of this valuable tax credit for parents.
