Abstract: To address the problem of high complexity of channel estimation for orthogonal time frequency space (OTFS) systems, we propose a low complexity channel estimation method leveraging the ...

Abstract: Orthogonal Time Frequency Space (OTFS) modulation offers a novel solution for high-mobility communication. However, iterative channel estimation and detection methods with high complexity ...

The program runs each method 100 times to measure average execution time and compares the performance against expected computational complexity. Cramer's Rule computes each variable xᵢ as the ratio ...

It is not easy to make collective sense of democracy in America at this moment. On the one hand, many of the institutions that have long anchored our system of ordered liberty remain in place, e.g., ...

Follow the space program since the moon landing in the four-part documentary "Once Upon a Time in Space". Here’s how to watch it anywhere on the planet. When you purchase through links on our site, we ...

Leaders are under relentless pressure to perform in an environment of increasing uncertainty and change. Many feel stuck, relying on planning, control, technical expertise, and other familiar ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

Forbes contributors publish independent expert analyses and insights. Nathan Goldman is a tax prof. at NC State Univ. If Trump’s tariffs in the year 2025 have taught us anything, it is that tax policy ...

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...
