A frequency domain diversity DVB receiver device includes multiple antenna
ports for receiving radio signals, and radio signal processing circuits
connected to the antenna ports that convert the received radio signals
into digital samples. The digital samples from the different antenna
ports time-share a front-end processor which processes the digital
samples to provide time-domain symbols. The time-domain symbols are
stored in time-domain symbol buffers according to which of the antenna
ports the time-domain symbols are received. A fast fourier transform
circuit then retrieves the time-domain symbols and converts them
frequency-domain symbols, which are then stored one or more
frequency-domain symbol buffers according to the antenna ports the
corresponding radio signals are received. A diversity processor which
combines the frequency-domain symbols from the frequency-domain symbol
buffers.
