Abstract
A channel estimation method for use in a wireless communication system, the system comprising a source apparatus and a destination apparatus, the source apparatus being operable to transmit information to the destination apparatus, the method comprising: allocating transmission frequency bandwidth over a particular time period into a plurality of contemporaneous pilot transmission blocks each having a frequency bandwidth profile; assigning pilot signals for transmission at selected time-frequency positions within each of the pilot transmission blocks; and in the particular time period, transmitting information and the pilot signals of at least one of said pilot transmission blocks from the source apparatus to the destination apparatus.
