| Abstract: | Increasing need for high data rate transmission and reliability of communication over fading channels using multiple transmit antennas has drawn attention to high spectral efficiency modulation schemes such as Quadrature Amplitude Modulation (QAM). With the aim of increasing the 'Diversity Order' of signal set we consider multidimensional rotated QAM constellation. Increasing diversity order 'L' is not the only design parameter, there are some other important parameters like minimum product distance 'dpmin' and the product kissing number 'τP which influence the system performance. In this paper, the suitable rotation has been worked out for Multidimensions using the 16QAM & 64QAM constellations and the corresponding kissing numbers have been checked. The combined architecture for MIMO (multiple- input multiple- ouput) Antenna system involving the concept of rotated constellation and concatenated with trellis coded modulation (TCM) is designed and simulated using the low complexity lattice decoder at the receiver. The performance of rotated and non-rotated constellation with Channel State Information (CSI) error has been evaluated. [ABSTRACT FROM AUTHOR] |
