Hybrid access scheme based on one-phase preamble and channel monitoring/assignment for satellite communications

In this letter, we propose a hybrid access scheme for satellite communications, taking into account the long propagation delay. The proposed scheme uses the one-phase preamble of 3GPP2 for fast access and applies the channel monitoring/assignment scheme of 3GPP for more reliable transmission. The results of analysis and simulation show that the proposed scheme achieves high throughput and low delay according to propagation delays in satellite communication environments.
