Abstract :
We propose several techniques for the HomeRF system. A DC-offset compensation technique and a decision directed channel estimation technique are proposed Because they use a TS field as reference information for initial training, the proposed techniques require no additional training sequence and only a little additional complexity. And finally, turbo coding technique and space-time block coding technique are considered as improved coding schemes. According to the results of our simulations, the performances of the proposed techniques are significantly improved in comparison with the conventional HomeRF system.
