Abstract

A wireless communication system configured to communicate using a mixed waveform configuration. The mixed waveform includes a first portion modulated according to a single-carrier scheme with a preamble and header and a second portion modulated according to a multi-carrier scheme. The waveform is specified so that a CIR estimate obtainable from the first portion is reusable for acquisition of the second portion by the receiver. The transmitter may include first and second kernels and a switch, where switch selects the first kernel for the first portion and the second kernel for the second portion to develop a transmit waveform. The receiver may include a single-carrier receiver, a multi-carrier receiver, and a switch that provides a first portion of a signal being received to the single-carrier receiver and a second portion of the signal being received to the multi-carrier receiver.
