- Provided are a method for measuring a variable bandwidth wireless channel, and a transmitter and a receiver therefore. The transmitter, includes: a pre-processing unit for performing variable over-sampling and band-limited filtering on an original sequence for measuring the wireless channel according to a pre-determined digital-to-analog (D/A) operation speed and measurement bandwidth, and creating and storing a probing sequence whose frequency is up-converted into a fixed transmitting intermediate frequency; and a real-time processing unit for transmitting a probing signal that the stored probing sequence is converted according to the D/A operation speed to the wireless channel.
