摘要：

We propose a joint source-coding power-control approach combined with joint source-channel coding employing the class of rate-compatible codes for video transport over ode-division multiple-access networks. We show that this cross-layer approach can provide improved spectral efficiency and network use while exhibiting graceful degradation characteristics with an increasing number of users.
