A semi-single frequency network (SFN) concept is presented. According to
the SFN concept, the same data signal is transmitted from multiple base
stations to a mobile terminal simultaneously on the same frequency band.
Accordingly, the transmitted signals are combined in the radio channel
and the mobile terminal experiences the transmitted signals as one signal
propagated through a multipath channel. Additionally, each base station
transmits a base station specific pilot signal. The mobile terminal
carries out a channel estimation procedure for each received pilot signal
and combines the channel estimates to obtain information how to equalize
the received data signal. Then, the mobile terminal calculates
equalization weights from the combined channel estimates and equalizes
the received data signal.
