Can anybody explain carrier recovery and timing recovery of DQPSK.
I kown there are component as: PED,LOOP filter,NCO and complex multipler.
What kind of architeture of both carrier recovery and timing recovery of DQPSK?

i used to use a pll in verilog

 

[Puppet1]

get the gardner book on pll

has chapter on clock and timing recovery as well as carrier recovery.
also try haykin communications texts

carrier recovery is for synchronization
timing recovery is picking the time instant within the symbol period which provide you the highest SNR
