Hi All, I would be very grateful if some experts can give me their opinions about the following questions (from algorithmic perspective). (1) What has been/can be a good approach to a single carrier receiver design (synchronization, channel estimation, equalization, etc.) operating at low SNRs? How would you go about frquency, timing, phase synchronization and equalization algorithms? (3) What are the practical Es/No limits below which known algorithms simply don't work? (4) Finally, how important can the role of decoders be in something like iterative decoding and synchronization? Thank you.

Which is rude, the OP's asking someone to do his homework/test or Vlad's STUPIDENT comment? I think they both fall into the same category myself. Rick

If I know less about something, I ask a question. If someone doesn't like the question, s/he simply shouldn't respond. What is the benefit of showing someone how high you stand? I have seen much simpler questions than this being answered by reasonable folks here. And all I needed here was just some educated comments.>On 12/6/2012 9:48 AM, johan_mozart wrote: >>> >>> "commsignal"<58672@dsprelated> wrote in message >>> news:pNWdnSbWhfI_pV3NnZ2dnUVZ_rOdnZ2d@giganews.com... >>>> Hi All, >>>> I would be very grateful if some experts can give me theiropinions>>>> about the following questions (from algorithmic perspective). >>>> >>>> (1) What has been/can be a good approach to a single carrier receiver >>>> design (synchronization, channel estimation, equalization, etc.) >> operating >>>> at low SNRs?

That's all it takes.
