The authors consider a two user Discrete Memoryless Broadcast Channel (DMBC) with perfect feedback from both the receivers. The best known achievable region for the general DMBC without feedback is known as the Marton's region, where the achievable strategy employs random coding. By effectively using the available feedback, they construct explicit coding schemes which achieve any rate-pair in the Marton's region. It is well known that feedback does not increase the capacity of a point to point Discrete Memoryless Channel (DMC). However, it can drastically improve the error performance.
