Transmitter to generate an analytic signal for reduced inter-symbol interference (ISI)

摘要

A system and method for receiving a plurality of pilot tones, generating an analytic signal in a frequency domain, the analytic signal including frequency components that when converted to a time domain include a preamble having a first half containing only non-zero data and a second half containing only zero data, converting the analytic signal from the frequency domain to the time domain, resulting in the preamble having the first half containing only non-zero data and the second half containing only zero data, generating a cyclic prefix based on the second half of the preamble, and attaching the cyclic prefix to the preamble to form a pilot signal, the cyclic prefix including only zero data.
