Receiving apparatus and method using multicarrier modulation
First Claim
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.

Abstract
An equalizing and error correcting section includes an equalizing section, an error processing sections, and a select section. The equalizing section outputs the received data subjected only to channel compensation and phase rotation compensation and the received data subjected not only to those compensations but also to power amplifier distortion compensation. These two received data items are subjected to an error process separately at the error processing sections. On the basis of the decisions at the error processing sections, the select section makes a final decision whether the receiving process has been successful or unsuccessful. That is, if either of the two decisions has been successful, the receiving process is regarded as successful. Only if both of the two decisions have been unsuccessful, the receiving process is regarded as unsuccessful.

10. A receiving method comprising:
-
subjecting reception data to a first correcting process, then carrying out an error process of the resulting data, and making a first decision whether said reception data has been received successfully or unsuccessfully; subjecting said reception data to a second correcting process, then carrying out said error process of the resulting data, and making a second decision whether said reception data has been received successfully or unsuccessfully; and making a final decision whether said reception data has been received successfully or unsuccessfully on the basis of said first and second decisions; wherein said first correcting process includes correcting the characteristic of a transmission path and 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 correcting the characteristic of a transmission path, correcting phase rotation caused by at least a frequency offset and the clock difference between a transmitter and a receiver, and correcting power amplifier distortion caused at a power amplifier in the transmitter. - View Dependent Claims (11, 12, 13, 14, 15, 16)
