Adpative PSK system and timing offset compensation circuit

摘要

The present invention provides for an adaptive modulation capable of modulating data selectively according to a BPSK or a QPSK scheme, wherein the adaptive modulator 21 is designed such that the constellation points of the BPSK scheme are a subset of the constellation points of the QPSK scheme. The present invention furthermore relates to a demodulator for demodulating data in the cited manner and furthermore comprising a timing offset compensation unit 1, 2, 3. The invention proposes different implementations of a timing compensation unit which is independent of the actually used modulation scheme.
