Index Modulation for 5G: Striving to Do More with Less

Index Modulation for 5G: Striving to Do More with Less

The fifth generation (5G) wireless communications brag both high spectrum efficiency and high energy efficiency. To meet the requirements, various new techniques have been proposed. Among these, the recently-emerging index modulation has attracted significant interests. By judiciously activating a subset of certain communication building blocks, such as antenna, subcarrier and time slot, index ...

Do more guns cause less crime?

The main argument of a recent book by John Lott is summarized in the title: More Guns, Less Crime [26]. There are three parts to this argument: 1. that there were more guns 2. that there was less crime 3. that more guns caused less crime Lott’s argument depends on all three parts being true. If any one of the parts is incorrect, the entire argument fails. In fact, as I will show in the next thr...

Deconstructing the Deformable Parts Model: Do More with Less

The deformable parts model (DPM) [1] is a successful detection model that continues to achieve state-of-the-art results in object detection. While the model’s success is attributed to the deformable parts, the proposed system has many other design choices such as the use of multi-resolution HOG features, the sampling of parts from high energy areas, the use of a mixture model, etc. Recently, th...
