WIRELESS TRANSMITTING APPARATUS AND PRE-EQUALIZATION METHOD THEREOF

摘要

A wireless transmitting apparatus capable of improving the reception error rate of a wireless receiving apparatus. In the inventive apparatus, a channel estimating part (122) acquires a propagation path estimated value. A control part (113) determines whether an estimation precision of the acquired propagation path estimated value is equal to or greater than a predetermined level. A pre-equalization (PE) part applies PE based on the acquired propagation path estimated value to a transport signal if it is determined that the estimation precision is equal to or greater than the predetermined level. Otherwise, the pre-equalization (PE) part avoids the PE application to the transport signal. An RF part (117) transmits the transport signal to which PE has been applied, and transmits the transport signal for which the PE application has been avoided.
