Gravitational waves (GWs) are one of the key signatures of cosmic strings. If GWs from cosmic strings are detected in future experiments, not only their existence can be confirmed but also their properties might be probed. In this talk, I will present the determination of cosmic string parameters through future GW experiments. We consider two types of direct detection GW signals, bursts and the stochastic GW background, which provide us with different information about cosmic string properties. The two different types of GW can break degeneracies in some of parameters and provide better constraints than those from each measurement. In addition, indirect detection of GW background through CMB B-mode and/or pulsar timing experiments provide independent information from direct detection experiments. I will also show how these different types of experiments help to constrain cosmic string parameters.
