Integrated Approach to Demodulation and Decoding of Convolutionally Coded and Orthogonally Modulated DS-CDMA Signals
The system under study is a convolutionally coded and orthogonally modulated DS-CDMA system in time-varying frequency selective Rayleigh fading channels. After convolutional encoding and block interleaving, information bits are mapped to Mary orthogonal Walsh sequences. In conventional systems, Mary symbol demodulation and convolutional decoding are conducted separately in the receiver, only ha...
متن کاملRate control for DS-CDMA wireless systems using power control and orthogonally coded substreams
There is an increase of multimedia applications in wireless networks. The increase in data transmission requirements for some multimedia applications poses a problem for the service providers who must overcome the high interference environment to provide this higher transmission rate. One method to service multimedia users is by splitting their data streams into separately coded substreams. We ...
متن کاملConvolutionally - Coded and Spectrum - Overlapped Multicarrier DS - CDMA Systems in a Multipath Fading Channel
Jung-Hun Oh et al. 177 Multicarrier DS-CDMA is an effective approach to combat fading and various kinds of interference. In this paper, we present an overlapped multicarrier DS-CDMA system, wherein each of the rate M / 1 convolutionally-encoded symbols is also repetition coded and transmitted using overlapped multicarriers. However, since the frequency spectrums of successive carriers are allow...
متن کاملPerformance analysis of convolutionally coded DS-CDMA systems with spatial and temporal channel correlations
Combined spatial and temporal processing has been shown to increase the potential link capacity enormously for wireless communication systems, especially when the channels between different transmit and receive antenna pairs are uncorrelated. In this paper, we consider both spatial and temporal channel correlations that may be encountered in space-time processing and present the performance ana...
متن کاملIterative Detection, Decoding and Channel Parameter Estimation for Orthogonally Modulated DS-CDMA Systems
In this thesis, we study iterative detection, decoding and channel parameter estimation algorithms for asynchronous direct-sequence code division multiple access (DS-CDMA) systems employing orthogonal signalling formats and long scrambling codes. Multiuser detection techniques are widely used to combat the detrimental effects of multipath fading and multiple access interference (MAI), which are...
