Abstract

The present invention relates to methods of transmitting signals, a receiver, and methods of receiving signals. In particular, the present invention relates to methods of transmitting signals having pilots exhibiting a scattered pilot pattern, wherein each pilot of the scattered pilot pattern corresponds to an index of each transmitter among a predetermined number of transmitters. In addition, the present invention relates to a receiver performing echo estimations based on scattered pilots (SP) and scattered adjacent pilots (SAPs) inserted in received symbols, wherein the SAPs comprise a plurality of pilot groups having an identical index of a transmitter among a predetermined number of transmitters structured in the symbols exhibiting a scattered pattern in a frequency domain.
