摘要： There are provided techniques for transmitting, receiving and coordinating pilot sequences, and for evaluating channel properties. A pilot signal may comprise a pilot sequence, which comprises a plurality of symbols with: at least one first set of equally spaced symbols (SA), and at least one second set of equally spaced symbols (SC), the symbols of the at least one second set of equally spaced symbols (SAC) being inserted in between the symbols of the at least one first set of equally spaced symbols (SA). It is possible to select: the at least one first set of equally spaced symbols (SA) in such a way that each first set of equally spaced symbols represents a respective first code and the at least one second set of equally spaced symbols (SE) in such a way that each second set of equally spaced symbols represents a respective second code, each first code and each second code may be selected from a set of codes in which each code (SA, SC) of the set of codes is orthogonal to at least one other code (SE, SG) of the set of codes. The same technique may be implemented at another transmitter, which transmits sequences using codes orthogonal to the codes transmitted by the transmitter.
