  • Abstract Two noncoherent block coding schemes, noncoherent block-coded 8PSK (NBC-8PSK) and noncoherent block-coded Twisted amplitude and phase shift keying using eight signal points(NBC-8TAPSK) were proposed, respectively. However, the data rate is not high since only eight signal points are used in both schemes. In this thesis, we discuss noncoherent block coding scheme with sixteen signal points, including 16TAPSK and quadrature amplitude modulation (16QAM). 16QAM is widely used for coherent communication. We derived the minimum noncoherent distance for block-coded 16QAM. Accordingly, we propose a new noncoherent block coding scheme. For different block length and code rate, NBC-16TAPSK and NBC-16QAM are compared by distance analysis and computer simulations.
