According to this problem,in this paper,a new reliable multicast protocol is proposed which integrates packet-level FEC and rate-adaptive technology on the basis of unidirectional satellite link.

Performance analysis of IEEE 802.11 multirate networks with rate adaptation

Wireless Ad Hoc network is a new kind of network which studies about its MAC layer rate adaptation technology that is helpful in increasing the throughput of network.

In the MAC layer s research, there’re some key technical problems need to be solved, including hidden terminal problem, exposed terminal problem and fairness problem, as well as QoS guarantee, rate adaptation and so on.

A Novel Rate-Adaptive MAC Protocol for Ad Hoc Networks;

Background subtraction using gaussian mixture models based on adaptive learning rate;

The contribution is given to a method that the bounds of learning rates in networks different layers can be obtained by the data from the individual system, from which the initial value and method of adaptive learning rate can be confirmed and the optimum learning rates can be gained.

By the use of the additional momentum method and adaptive learning rate of BP network, a neural network model was established to calculate the speed of tidal bore.

To avoid the waste of system capacity by using mono speech codec and rising utility of frequency, GSM Phase 2+ give a solution as Adoptive Multi-Rate (AMR) speech codec which be adopted as speech codec standard in 3GPP.

AMR speech codec has eight rates, each of which is based on ACELP.

This paper,referring to 3GPP TS,gives an in-depth study on AMR,and carries out a detailed analysis on the working principle of AMR.
