Hi All, I'm looking at ASIC and CMOS implementations on carrier and timing recovery for wireless receivers. I would like to know operating ranges, accuracy, speeds, compatibility and power consumption of different algorithms. As the first step, I would like to refer some popular publications on this area. Im mainly focused on PLL based timing and carrier recovery circuits and feed forward based algorithms. I appreciate if someone can suggest approprite readings/publications to start my work. Thanks.

I have already refered these texts. They cover only theoratical parts not hardware implementations. I need implmentations FPGA, ASIC and CMOS. Anyone familiar with hardware implementations?

It's kind of like asking what tire is best for a car. What kind of car? What conditions? How will the car be used? etc., etc... The only thing I'd answer generally is that FPGAs require more power than the same thing implemented in an ASIC. Other than that a good answer for everything you've asked is "It depends."

Get an ABC book on digital communication; such as "Digital Communication" by Sklar or "Digital Communication" by Proakis. VLV

I have implemented some common frequency and timing recovery algorithms in Matlab. I want to look at how to implement them on hardware. I assume that all those algorithms must have implemented in hardware and hence I need to get some information. E.g. Gardner timing detector, Kay frequency estimator.> > > > Get an ABC book on digital communication; such as "Digital > > Communication" by Sklar or "Digital Communication" by Proakis. > > > > VLV

Which one? >>> I want to start from some where. Could you please consider GSM ?GSM is designed for batch processing. That is, burst signal is sampled in a buffer and then processed. Sync and carrier are established by search for max. likelihood using predefined sequence in the middle of the burst. Vladimir Vassilevsky DSP and Mixed Signal Designs www.abvolt.com
