We proposed four types of differential modulation to map the unitary code into the OFDM signal. The time-varying channel model is established and the norm of detection metric is deduced. The norm is the inherent interference of the time-varying channel, so we can use it as criterion to evaluate the performance of our mapping schemes. The simulation results agree with the analytic conclusion.
