The combined automatic repeat request and rate control mechanism in S-band mobile interactive multimedia asynchronous return link—design background, parameter dimensioning and first experimental results

2016-02-10T09:53:03+00:00

SUMMARY In the S-band mobile interactive multimedia specification, an asynchronous access using Enhanced Spread Spectrum Aloha random access has been defined for occasional messaging applications. This access scheme is complemented by a combined automatic repeat request and terminal rate control mechanism that is described in this paper. Furthermore, a queuing theory-based model is developed to [...]

Enhanced spread Aloha physical layer design and performance

2016-02-10T09:53:13+00:00

SUMMARY This paper describes the key design and performance aspects of the Enhanced Spread Spectrum Aloha (E-SSA) physical layer, which represents an essential component of the S-band Mobile Interactive Multimedia European Telecommunication Institute standard. Thanks to advanced signal processing at the gateway side, the E-SSA random access protocol allows to achieve unprecedented spectral efficiency in [...]
