摘要：

In this letter, we propose a hybrid access scheme for satellite communications, taking into account the long propagat tion delay. The proposed scheme uses the one-phase pireamble 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.
