“…Since the set of the transmission strategies with is sufficient by Corollary 1, the set of all the transmission strategies satisfying (7)- (9) is also sufficient.

“…In [8], LDPC codes provided reliable transmission over two-user broadcast channels with additive white Gaussian noise (AWGN) and fading known at the receiver only. In [9], a superposition turbo coding scheme performs within 1 dB of the capacity region boundary for broadcast Gaussian channels. Both of these approaches are designed specifically for broadcast Gaussian channels and used linear codes.…”

Abstract-This paper provides an explicit expression for the capacity region of the two-user broadcast Z channel and proves that the optimal boundary can be achieved by independent encoding of each user. Specifically, the information messages corresponding to each user are encoded independently and the OR of these two encoded streams is transmitted. Nonlinear turbo codes that provide a controlled distribution of ones and zeros are used to demonstrate a low-complexity scheme that operates close to the optimal boundary.

We consider unequal error-protection schemes obtained by means of two-level superposition coding. The performance over additive white Gaussian noise channels is investigated for optimal maximum-likelihood decoding as well as for a suboptimal decoding strategy based on interference cancellation. Assuming that linear codes are used, we evaluate, for both strategies, analytical approximations of the word-error rate, based on the union bound. As in the case of turbo codes and turbo-coded modulations, the derivation exploits the concept of uniform interleaving, and the bounds are in excellent agreement with the simulation results obtained using iterative decoding. The analytical expressions are useful for code design and for the selection of decoding strategies providing a suitable performance/complexity tradeoff.

We consider unequal error-protection schemes obtained by two-level superposition coding. While the existing schemes implement superposition by means of linear modulations, we propose superposition implemented through continuous phase modulations (CPMs). In the considered scheme, unlike in the linearly-modulated ones, the transmitted signal has constant envelope and thus the system does not rely on the presence of expensive amplifiers. We investigate the potential of CPMs for multi-rate transmissions over channels impaired by additive white Gaussian noise. Particularly, we derive the relevant algorithm for maximum-a-posteriori symbol detection, evaluate the ultimate information rate, and design practical coding schemes that perform fairly close to the theoretical limits.
