The following thread may be helpful:
Designing a cross-correlator in HDL would be a difficult task, even for someone experienced in HDL-based FPGA design, unless they have done one before.
BTW, please don't shout.

the thread you provided was very helpful in identifying the delay, thanks for that. Now i need to identify the multiple delays between two signals, for that i need to go for wigner distribution(i.e FFT of the auto correlation of the signal) of the signal.Could you please help me in identifying these multiple delays

These aren't FPGA-specific problems - have you modelled your system using a tool like Matlab? It is far quicker and easier to prototype and evaluate DSP algorithms in software tools. Once you've found a working solution, you can then implement it on your FPGA. In the meantime, a DSP-specific forum or an appropriate professor (if you're working at a university) might be more helpful.
