Multi-user Map Decoding for Flat-fading Cdma Channels
نویسندگان
چکیده
This paper presents a multiuser maximum a posteriori (MAP) decoder for synchronous code division multiple access (CDMA) signals on Rayleigh at-fading channels. The receiver does not assume perfect channel information at the receiver. The key idea is to expand the decoding trellis for the purpose of joint channel estimation and decoding. The time varying channel eeect is equalized by coupling minimum mean square error channel estimation techniques with the trellis MAP decoding.

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملOn the Performance of Blind Chip Rate Estimation in Multi-Rate CDMA Transmissions Using Multi-Rate Sampling in Slow Flat Fading Channels
This paper considers blind chip rate estimation of DS-SS signals in multi-rate and multi-user DS-CDMA systems over channels having slow flat Rayleigh fading plus additive white Gaussian noise. Channel impulse response is estimated by a subspace method, and then the chip rate of each signal is estimated using zero crossing of estimated differential channel impulse response. For chip rate estimat...
متن کاملA Robust Technique for Blind Multiuser CDMA detection in Fading Channels
This paper considers the blind multiuser reception problem for Direct Sequence Code Division Multiple Access (DS-CDMA) systems. A hybrid approach to the blind reception of linear multiple-input multiple-output (MIMO) channels is taken up. We consider the problem of blind detection of multiuser CDMA signals in a space time scenario. The channel is assumed to have a small scale flat fading behavi...
متن کاملIterative Detection for Mc-cdma System with Base Station Antenna Array for Fading Channels
Performance of a Multi-Carrier CDMA (MC-CDMA) system using iterative detection over a fading channel can be improved by incorporating antenna diversity at the base station (BS). In this paper we propose a new MC-CDMA system with multiple BS antennas to combat fading eeects. We consider only the uplink of a mobile in a terrestrial cell and derive the frequency selective MC-CDMA channel model usi...
متن کاملIterative Multiuser Decoding of Narrowband Signals in Fading Channels
In this paper we investigate multiuser detection techniques for coded narrowband signals in fading channels. In [1], Moher proposed a suboptimal multiuser detector and its performance is demonstrated for the AWGN channel. In this paper, this multiuser detector is modified for fading channels, such as the Rayleigh fading channel model. The fading channels described and simulated are flat narrowb...
