| Abstract: |
| Research in the emerging space industry is becoming attractive. One compelling area of current space research is the design of miniaturized satellites, known as CubeSats. Miniaturized satellites are enticing because of their numerous applications and low design-and-deployment cost. One of its challenges are the limited power resources. In this paper regular triangular quadrature amplitude modulatin (TQAM) is considered for this purpose for enhancing power resources with enhancing bit error performance. TQAM and SQAM are examined and simulated using GNUradio. The performance of 16 TQAM over satellite channel is compared with that of 16 QAM using GNUradio. Satellite links are currently being developed to provide higher data rates and improved power efficiency, i.e. lower average transmit power for a given error rate. Higher data rate is employed using higher order modulation scheme with good channels. A triangular lattice provides the most compact QAM constellations, i.e. constellation points closest to the origin . |
