Comparison of Psk and Dpsk Modulation in a Coded Ofdm System
نویسنده
چکیده
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 convolutionally coded OFDM systems.

"Turbo DPSK": iterative differential PSK demodulation and channel decoding
Multiple-symbol differential detection is known to fill the gap between conventional differential detection of PSK ( -DPSK) and coherent detection of -PSK with differential encoding ( -DEPSK). Emphasis has been so far on soft-input/hard-output detectors applied in uncoded systems. In this paper, we investigate a receiver structure suitable for coded DPSK signals on static and time-varying chann...
متن کاملCoded Modulation for Dpsk on Fading Channels
| Coded modulation for di erentially encoded PSK with non{coherent reception on at fading channels is considered. We derive theoretical limits on the performance and show how to design multilevel coding schemes and bit{interleaved coded modulation. Since Gray labeling is not possible for multiple symbol di erential detection and PSK constellations, bit{interleaved coded modulation exhibits seve...
متن کاملUsing WPT as a New Method Instead of FFT for Improving the Performance of OFDM Modulation
Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...

متن کاملDPSK versus pilot-aided PSK MAP equalization for fast-fading channels
This letter compares pilot-aided phase-shift keyed (PSK) and differential PSK (DPSK) modulation when using new maximum a posteriori joint channel estimation and equalization receivers with frequency-selective fast-fading channels. We conclude that pilot-aided PSK has superior bit-error rate performance in this case. However, at low signal-to-noise ratio, performance is similar, and DPSK is comp...
