A wireless communication system, a transmitting device and a receiving unit that attain an excellent error rate characteristic without depending on a propagation environment are provided. A wireless communication system has a transmitting device and a receiving device that perform communication by using a multi-carrier signal in which plural pilot signals are allocated in a direction of a time axis and in a direction of a frequency axis, wherein the receiving device comprises a quality generating means generating each piece of receiving quality information on each pilot channel for transmitting each pilot signal, a determining means determining the number of pilot channels needed in the multi-carrier signal based on the receiving quality information, and a notifying means transmitting a signal requesting the determined number of pilot channels to the transmitting device, and the transmitting device comprises an allocation means determining allocations of pilot signals in the direction of the time axis and in the direction of the frequency axis, corresponding to a requested number of pilot channels, and a transmitting means transmitting the multi-carrier signal having the determined pilot signal allocations. |
