Data-aided channel estimation for turbo-PIC MIMO detectors

M. Khalighi, J.J. Boutros, J.-F. Helard
2006 IEEE Communications Letters  
We consider data-aided channel estimation for multiple input multiple output (MIMO) systems when iterative parallel interference cancellation (PIC) is performed for signal detection.  ...  As a side contribution, we also showed the interest of using turbo-PIC for M R > M T /2. Manuscript received October 17, 2005.  ...  Let us first compare the performances of the turbo-PIC and turbo-MAP [5] detectors when perfect channel state information (CSI) is available at receiver.  ...

Performance of ds-cdma systems with optimal hard-decision parallel interference cancellation

R. van der Hofstad, M.J. Klok
2003 IEEE Transactions on Information Theory  
We investigate the exponential rate of the BEP after several stages of HD-PIC.  ...  These estimates show that the BEPs are quite small as long as = ( log ) when the number of stages of HD-PIC is fixed, and even exponentially small when = ( ) for the optimal HD-PIC system, and where is  ...  Interference cancellation, especially hard-decision parallel interference cancellation (HD-PIC), is a promising and practical technique for uplink receivers (see [18] ).  ...

While in stellar properties HD 131835 resembles β Pic, its dust disk properties are similar to those of the most massive young debris disks.  ...  If the gas is secondary, arising from the disruption of planetesimals, then HD 131835 is a comparably young and in terms of its disk more massive analogue of the β Pic system.  ...  For HD 21997 and β Pic the mass estimates were taken from the literature or from Table 1.  ...
