Abstract
In a communication system, a transmitter receives an input bit, and in response thereto, generates at least an n-bit codeword, each bit of which is generated by a respective one of n generators of which m are exactly the same, m being greater than n/2. A receiver comprises: m detectors, each adapted to receive the bit generated by a respective one of the m generators, and provide a respective one of m partial detection signals if a strength of the received bit exceeds a predetermined minimum threshold; and a majority logic element adapted to receive each of the m partial detection signals, and provide an output bit indicative of the input bit only if more than m/2 of the received m partial detection signals exceeds the minimum threshold.
