ABSTRACT:
The invention relates to a receiving system and method, and in particular, to a diversity receiving system and method. A diversity receiving system comprises a plurality of cascading receivers for combining a plurality of weighted bit metric streams corresponding to a plurality of radio frequency signals to output a final combined bit metric stream from a final receiver. Each receiver comprises an antenna for receiving a RF signal from a transmitter; a tuner coupled to the antenna for selecting a predetermined channel from the RF signal to generate an input analog signal; and a demapping and combining module coupled to the tuner and a previous demapping and combining module of a previous receiver for performing demapping and combination to generate a combined bit metric stream according to the input analog signal of the tuner and a previous combined bit metric stream of the previous receiver.
