Transmitter and receiver

The transmission apparatus used in a mobile communication system employing a single carrier scheme in an uplink, transmitting a transmit symbol including the multiplexing means to multiplex a pilot channel, a control channel and a data channel, a pilot channel and the control channel at least in uplink It comprises transmission means for,. The first pilot channel for measuring the channel state of the uplink from the receiving apparatus is transmitted in a frequency band over a plurality of resource blocks. A second pilot channel for compensating for a channel transmitted by the uplink is transmitted in a resource block allocated to the local station. The control channel of the local station and other station are orthogonal to one another in FDM manner. Mobile communication, a transmitting apparatus, receiving apparatus, a single-carrier multiplexing
