of  the following blocks used for the simulation of ofdm modulation
and demodulation(with out directly using ofdm mod and ofdm demod
blocks)

1. ofdm carrier allocator
2. fft
3.cyclic prefix
4.channel model
5.channel estimation
6.equilizer
7.serializer

could you please explain the parameters of each of this block with an
example.

You can find examples in gr-digital/examples/ofdm.

For 1. and 7. consult the manual, for the rest any textbook on OFDM.
