Abstract:
A circuit, comprising:a correction circuit coupled to receive a first estimate signal, a second estimate signal, and a plurality of input signals from an external source along plural signal paths, the plurality of input signals including a first and a second input signal, the correction circuit producing a first symbol estimate in response to the first and second estimate signals and the first and second input signals, the correction circuit producing a second symbol estimate in response to the first and second estimate signals and the first and second input signals; a combining circuit coupled to receive a plurality of first symbol estimates including the first symbol estimate and a plurality of second symbol estimates including the second symbol estimate, the combining circuit producing a first symbol signal in response to the plurality of first symbol estimates and producing a second symbol signal in response to the plurality of second symbol estimates; and a synchronization circuit coupled to receive the first and second symbol signals and a first known symbol and a second known symbol, the synchronization circuit producing a synchronization signal in response to an approximate match between the first symbol signal and the first known symbol and between the second symbol signal and the second known symbol.
