TL;DR: A low complexity optimization algorithm for the design of optimal constellation schemes for bit-interleaved coded modulation (BICM) systems and shows a significant improvement in terms of system performance and BICM channel capacities under additive white Gaussian noise and Rayleigh independently and identically distributed channel conditions.

TL;DR: The power-based non-orthogonal multiplexing (P-NOM) technology is proposed in addition to the existing orthogonal time-division-multiplexed (TDM) scheme, and a key finding is that using a two-layer P-Nom can essentially deliver a broadcast service on top of a unicast network, each achieving nearly full capacity.

TL;DR: A two-layer LDM with one layer used for providing a global service through a single frequency network (SFN), and the other for providing local coverage/services, such as location targeted advertising or local content insertion is studied.

TL;DR: In this paper, an on-channel repeater consisting of a receiver for receiving radio frequency (RF) signals and converting them into baseband signals, a subtractor for subtracting replicas of feedback signals from the baseband signal to produce signals whose feedback signals are primarily removed, and a demodulator for demodulating the signals which include the remaining feedback signals.

TL;DR: In this paper, the authors proposed a wireless in-band distribution link (WIDL) technology, where the distribution data is delivered to the newly deployed transmitters from the existing DTV towers wirelessly sharing the same TV band with the broadcast services.
