1. A method of determining channel impulse responses of a plurality of channels to a communication device, the method comprising:

  • performing transform operations on both a replica of a signal sequence sn and a received training sequence yn received by the communication device in at least one burst, the received training sequence yn being the signal sequence as received through a channel, the transform operations arranged to generate a multiplicity of signal sequence frequency bins and a multiplicity of training sequence frequency bins;

    performing point-by-point operations between corresponding signal sequence frequency bins and training sequence frequency bins; and

    concatenating the point-by-point operations associated with the channel to provide a composite frequency response for the channel, the composite frequency response allowing, in the time domain, generation of the channel impulse response for the channel.
