Codeword or Noise? Exact Random Coding Exponents for Joint Detection and Decoding

We consider the problem of coded communication, where in each time frame, the transmitter is either silent or transmits a codeword from a given (randomly selected) codebook. The task of the decoder is to decide whether transmission has taken place, and if so, to decode the message. We derive the opt...
