1. A receiving apparatus comprising:
an equalizing section which subjects reception data to a first correcting process and to a second correcting process different from said first correcting process;
a first error processing section which carries out an error process of said reception data subjected to said first correcting process and makes a decision whether said reception data has been received successfully or unsuccessfully;
a second error processing section which carries out an error process of said reception data subjected to said second correcting process and makes a decision whether said reception data has been received successfully or unsuccessfully; and
a select section which makes a final decision whether said reception data has been received successfully or unsuccessfully on the basis of the decisions at said first and second error processing sections;
wherein said first correcting process includes a process of correcting the characteristic of a transmission path and a process of correcting phase rotation caused by at least a frequency offset and the clock difference between a transmitter and a receiver; and
wherein said second correcting process includes a process of correcting the characteristic of a transmission path, a process of correcting phase rotation caused by at least a frequency offset and the clock difference between a transmitter and a receiver, and a process of correcting power amplifier distortion caused at a power amplifier in the transmitter.
