Comparison of Psk and Dpsk Modulation in a Coded Ofdm System

  title={Comparison of Psk and Dpsk Modulation in a Coded Ofdm System},
  author={Hermann Rohling and Thomas May},
AbsfrucfOrthogonal Frequency Division Multiplexing (OFDM) [l] is often proposed for high data rate transmission over frequency-selective channels in order to simplify equalisation. In this paper 4and &PSK and DPSK with coherent and non-coherent demodulation are considered for performance comparison. A channel estimation and equalisation is necessary for coherent demodulation whereas this effort is not required in the case of non-coherent detection. The performance comparison is made for… CONTINUE READING
