The Channel Alliance participants use a wide variety of channel sounder architectures. Most fall into three major categories: VNA-based, correlation-based, and FMCW (chirp). Each is described briefly here. As well, because many channel sounder architectures rely on precise timing between the transmitter and the receiver or between antenna positions, there is a section devoted to synchronization techniques used by participants.
