Abstract
In absence of user data, a bit extracting portiontreats pilot bits as pseudo user data and delivers the pilot bits to a pilot converting portion. The pilot converting portioncarries out symbol rotation with reference to a bit pattern in case where CRC bits alone are transmitted. Those symbols are decoded by a deinterleaving portionand an error correcting portion. A CRC judging portioncarries out CRC judgment.
