Efficient channel estimate based timing recovery
Abstract:
A module and method for channel estimate based timing recovery comprises a timing estimation module, a channel estimation module communicably coupled to the timing estimation module, a conversion module communicably coupled to the timing estimation module and to the channel estimation module, and an analog pulse shaping filter communicably coupled to the conversion module, wherein: the analog pulse shaping filter receives an analog signal and outputs a filtered analog signal, the conversion module receives the filtered analog signal and outputs a 1/T rate signal to the channel estimation module, the channel estimation module outputs a 1/T Channel Impulse Response (CIR) estimate to the timing estimation module, and the timing estimation module outputs a timing estimate to the conversion module, wherein the timing estimate is used in conjunction with an output of the conversion module to provide the 1/T rate signal.
