Identification via the Broadcast Channel

The Static Broadcast Channel

In this paper we present a different view on the broadcast channel that fits better an asynchronous setting, where each receiver can “listen” to the broadcasted data at different time intervals. In the scenario we suggest, there is a “static” fixed amount of data, that needs to be transmitted to all receivers. Each receiver wants to minimize the receiving time, and this way to get the static da...

MIMO Broadcast Channel

Approximate Channel Identification via -Signed Correlation

A method of approximate channel identification is proposed that is based on a simplification of the correlation estimator. Despite the numerical simplification (no multiplications or additions are required, only comparisons and an accumulator), the performance of the proposed estimator is not significantly worse than that of the standard correlation estimator. A free (user selectable) parameter...

Interactive Coding Over the Noisy Broadcast Channel

A set of n players, each holding a private input bit, communicate over a noisy broadcast channel. Their mutual goal is for all players to learn all inputs. At each round one of the players broadcasts a bit to all the other players, and the bit received by each player is flipped with a fixed constant probability (independently for each recipient). How many rounds are needed? This problem was fir...

Trellis precoding for the broadcast channel

This paper considers the vector Gaussian broadcast channel where a single transmitter with multiple antennas sends independent information to multiple receivers. An achievable rate region is derived by decomposing the broadcast channel into a series of single-user channels with non-causal side information. The side information may be completely pre-subtracted using precoding techniques. A pract...
