Abstract
This paper presents a new method, referred to as the cocktail intra-symbol-code, to reveal the possibility of exceeding the channel limit of QPSK input by transmitting independent signals in parallel manner and separating them the receiver, repetitively. In the proposed modulation scheme, the rhombic constellation is created to work with the modulated signal and the channel code in Euclidean- and Hamming space cooperatively. The theoretical derivations are done under the assumption of using the capacity-achieving codes and the results are shown in terms of the reliable bit rates.
