First Claim
Patent Images
1. A training sequence transmission in a radio communications system comprising:
- a core sequence of symbols;
a successive repetition of the core sequence, the repetition of the core sequence having a timing ambiguity; and
a marker sequence having a sequence of symbols different from the core sequence, the marker sequence resolving the timing ambiguity of the repetition of the core sequence.
