METHOD FOR CHANNEL ESTIMATION IN A RADIO COMMUNICATION SYSTEM WHEREBY THE CHANNEL MEASURING SEQUENCES ARE FORMED BY CYCLIC DERIVATION OF BASIC SEQUENCES

摘要

The invention relates to a method for channel estimation, whereby the amount of channel measuring sequences is expanded by using time-inverted channel measuring sequences. The time-inversions of the channel measuring sequences have the same characteristics as the original channel measuring sequences and are easily derived there from. A further advantage is that doubling of the amount of available channels is achieved without additional signaling or saving of additional channel measuring sequences being required. Said advantages can be obtained by simply redefining utilization of said channel sequences.
