Title : | Multiple Symbol Differential Detection of 2/4 MTCM using π/4 shift QPSK |

Conference : | Asia-pacific conference on communications |
Abstract : | In this paper, the idea of using a multiple symbol observation interval to improve error probability performance is applied to differential detection of MTCM with pi/4 shift QPSK and 8DPSK. We propose two types of sliding multiple symbol differential detection algorithm, type 1 and type 2. The two types of sliding detection scheme are examined and compared with conventional detection and block detection with these modulation formats in an additive white Gaussian noise (AWGN) using the Monte Carlo simulation. We show that the amount of improvement over conventional and block detection depends on the number of phases and the number of additional symbol intervals added to the observation. The analytical results of 2/4 MTCM is derived using pi/4 shift QPSK from the transfer function bound approach in AWGN. Computer simulation results are presented for 2,4,8 states in AWGN channel. |
