Pseudo random codes are easily constructed and can be used in multiple-input multiple-output (MIMO) radar to provide for signal separation. However it has the drawbacks of high aperiodic cross-correlation and auto-correlation sidelobes. Fortunately, in some applications, codes with low correlations are needed only over a narrow window. In this paper, we(More)
This paper firstly investigates an optimal parallel interference cancellation (PIC) scheme for DS/CDMA system. Secondly, to reduce the high implementation complexity encountered by the optimal PIC, we propose a reduced-complexity PIC. The performance of the reduced-complexity PIC over Rayleigh fading channel is analyzed and compared to the optimal PIC and(More)
— In this paper, we consider convolutionally coded multi-carrier DS-CDMA and propose Turbo partial parallel interference cancellation (PPIC) and decoding, which is termed Turbo PPIC/decoding. We make analysis and simulations for Turbo PPIC/decoding by the computer. The simulation results shows that Turbo PPIC/decoding, whether with a priori LLR feedback or(More)
It has been shown that Multiple-Input Multiple-Output radar can dramatically improve the performance of a radar. In this paper, the Direct Sequence Code Division Multiple Access(DS-CDMA) sequence are used as transmitting waveforms for the different antennas. Due to the high sidelobe of the code correlation, conventional code correlation range compression(More)
In this paper, parallel interference cancellation and decoding for convolutionally coded DS-CDMA systems is investigated. Firstly, we derive a reduced-complexity PIC/decoding (simplified PIC/decoding). Secondly, two forms of simplified PIC/decoding are analyzed, and compared with the exact PIC/decoding over Rayleigh fading channel. It shows that the(More)
