Abstract

There is an ever present demand for increasingly higher data rates in multi-spot beam satellite networks. This can be enabled, by shifting carrier frequencies to higher bands, such as the Q/V-band, where more bandwidth is available. Furthermore, the available bandwidth has to be used as efficiently as possible, which requires efficient capacity enhancing techniques. The present paper identifies and analyzes ground segment capacity enhancing techniques for ultra high throughput multi-spot beam satellite networks operating in Q/V-band in the feeder link and in Ka-band in the user link. The impact of several capacity enhancing techniques on system performance is analyzed using a realistic time step-based system simulator. Their impact on the ground segment costs is also analyzed. The examined capacity enhancing techniques are as follows: (i) reduced carrier spacing with adjacent channel interference cancellation; (ii) full frequency reuse with co-channel interference cancellation and scheduling; (iii) four different smart gateway diversity techniques and; (iv) employing optical feeder links as an alternative to radio frequency feeder links. The paper shows that these techniques are capable of improving system performance at the expense of an increase in cost related to the complexity and maturity of the applied capacity-increasing technique.
