A Linear Receiver for Coded

چکیده
| In this paper we consider a CDMA system with error control coding. Optimal joint decoding is prohibitively complex. Instead we propose a sequential approach for handling the multiple access interference and the error control decoding. The error control decoding is implemented via single user soft{input decoders utilising metrics generated by linear algebraic multiuser metric generators. The decor-relator, and a new scheme termed the projection receiver are utilised as metric generators. For a synchronous system the coded performance of the projection receiver metric is shown to be superior to the decorrelator even though they are equally complex. Also the theoretical degradation relative to the single user bound is derived.

متن کاملBlind multiuser detection for space-time coded CDMA systems
We propose here a linear blind multiuser detector, referred to as the Capon receiver, for space-time coded CDMA (code division multiple access) systems. The proposed Capon receiver is designed to pass desired signals without distortion, meanwhile minimizing the overall interference signals, irrespective of their origins. It is shown that the Capon receiver achieves similar performance in terms ...

In this paper, analytic expressions of upper bounds of the bit error probability provided by the MMSE receiver are derived for OFDM based systems when the number of carriers is large enough. Considering convolutive Forward Error Correcting schemes and QPSK constellations, it is shown that coded Linear Precoded OFDM (LP-OFDM) outperforms Coded OFDM (COFDM) if the input SNR is greater than a thre...

Data detection of convolutional coded differential quaternary phase shift keyed (DQPSK) signals using a predictive Viterbi algorithm (VA) based receiver, is presented for single input, multiple output orthogonal frequency division multiplexed (OFDM) systems. The receiver has both error correcting capability and also the ability to perform channel estimation (prediction). The predictive VA opera...
متن کاملCoded continuous phase modulation with low-complexity noncoherent reception
Coded continuous phase modulation based on a feedback–free modulator with noncoherent detection is discussed. Low–complexity receiver processing is achieved by using only two or three linear filters for demodulation and applying noncoherent sequence estimation with reduced–state Viterbi decoding and simple branch metric calculation. Overall, the proposed noncoherent receiver provides significan...
