By jointly using layered division multiplexing (LDM) and scalable hierarchical video coding (SHVC), ATSC 3.0 will be used to deliver service targeted to both mobile and traditional rooftop antenna receivers. Under this approach, a physical layer pipe

During the last few years, reclaiming TV spectrum for mobile broadband use has been a hotly debated topic in the telecommunications policy agenda. This paper evaluates two ways to improve spectrum efficiency to today's noise-limited single-transmitte

In response to a request from the industry members of the Advanced Television Systems Committee (ATSC) the U.S. Federal Communications Commission (FCC) has recently approved voluntary use by broadcasters of a new, non-backwards compatible technical s

ATSC 3.0 is likely to be used to deliver service targeted to mobile receivers as well as service to fixed rooftop antennas, likely using Scalable Hierarchical Video Coding (SHVC) to minimize total bitrate, and Layered Division Multiplexing (LDM) to m

We evaluate for the existing UHF U.S. TV stations two ways to increase the spectrum reuse to repack them in a smaller block without reducing the coverage or bandwidth of any TV station. One way is to increase the transmit power of each broadcaster's

In this paper, we evaluate the bit error rate (BER) of bit-interleaved coded modulation (BICM) receivers that operate with a priori information obtained from the decoder during the so-called turbo iterations. We use Bonferroni-type lower and upper bo

In the popular bit-interleaved coded modulation (BICM) the output of the channel encoder and the input of the modulator are separated by a bit-level interleaver. From the decoder's point of view, the modulator, the transmission channel, and the demod

We present a numerically efficient method to evaluate uncoded bit-error rate for arbitrary two-dimensional constellation and nonuniform signaling in fading channels. Compared to the bounding techniques, treating the problem at the same level of gener

We present a numerically efficient method to evaluate exactly uncoded bit error rate for transmission in fading channels. The presented method deals with arbitrary two-dimensional constellation, arbitrary bits-to-symbols mapping, and with non-uniform
