Differential Space Frequency Mapping Schemes and Norm Criterion
| Title: | Differential Space Frequency Mapping Schemes and Norm Criterion |
| Author: | Li, Jie; Yang, Yuhang |
| Abstract: | 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. |
