Systems and methods are provided for enabling lower-bandwidth hardware components to support higher data rates. In particular, aspects of the disclosed systems and methods use Raised Cosine pulse shaping in short-reach links to band limit the signal spectra and thereby enable existing, such lower-bandwidth components to support higher data rates.

Systems and methods for improved data transmission in short-reach links

A method for simulating and optimizing a digital to analog converter is disclosed. The method may include receiving a plurality of digital words. The method may also include determining an effective number of bits, a respective amplitude and a first amplitude correction amount for each digital word. Further, the first amplitude correction amount may be applied to each respective amplitude to generate respective first corrected amplitudes. A timing uncertainty may be determined which may be used to determine a second amplitude correction for each digital word. The second amplitude correction may be applied to each of the respective first corrected amplitudes to generate respective second corrected amplitudes. Next, a representation of an analog signal may be generated based in part on the second corrected amplitudes. Finally, a filter may be applied to the representation of the analog signal and then the representation of the analog signal is outputted.
