Small scale fluctuation can be described in two scenarios: timedispersive and frequency dispersive.
小尺度衰落可以从信道的时间色散性和频率色散性两方面进行研究。

The BER performance of rate 2/3 trellis coded 8DPSK OFDM over timedispersive channels is simulated. The design of trellis codes at different carriers numbers of OFDM is discussed.
