Abstract: A receiving apparatus and receiving method that obtain good decoding characteristics in a multipath environment or multi-user environment. A radio receiving section (110) performs predetermined radio processing on a reception signal received via an antenna (100). A channel estimation section (120) performs channel estimation for the propagation path of the received signal. An equalizer (130) generates a replica of the received signal and performs equalization, and eliminates a delayed wave component from the received signal. A channel de-interleaver (140) de-interleaves the direct wave component of the received signal. A space-time turbo decoder (150) performs space-time turbo decoding of the received signal. A data decision section (160) makes a hard decision on a soft output likelihood from the space-time turbo decoder (150), and obtains a space-time turbo decoding result. A channel interleaver (170) interleaves the space-time turbo decoding result, and outputs the result to the equalizer (130).
