....(Decision Feed Back Minimum Mean Square Error) demodulator. The DFE MMSE can be applied to the GSM system using the linear approximation of the continuous phase modulations (CPM) A previous work has been performed comparing space division multiple access to multi user detection on GSM signals in [7]. Unfortunately, in this paper, the authors did not take into account the fact that the GSM modulation is a staggered modulation in their non linear receiver leading to sub optimal results [8] The channel estimation problem that becomes more and more complex as the number of simultaneous ....

....according to [25, 39, 46] would alleviate the e ect of incorrect models. Example 2. Iterative design and a comparison to Kalman and LMS tracking. Consider the uplink of a TDMA based mobile cellular communication system in which two mobile users transmit at the same frequency in the same time slot [40, 41]. One of the users could represent a strong out of cell co channel interferer. A receiver with two diversity branches (multiple antennas or polarization diversity branches) detects both users u and u t simultaneously. We model the situation by ....

....also in the MIMO case. As in the scalar case, studies of MIMO DFEs have been based on one of two principles: Either a modelbased design of a DFE with a non causal feedforward filter [3] or a model or data based optimization of DFEs whose structure is fixed prior to the design [4] 5] [6]. In this paper, we provide tools for model based DFE designs and for understanding of their structural properties. In Section IV, we present a generalized DFE with several inputs and outputs, which minimizes the mean square error under the constraint of realizability. The design is based on a ....

....and to reject the interference. A MIMO channel model (6) with n d 1, can furthermore be used for designing multiuser detectors, which simultaneously detect several symbol streams. This approach was first studied by Winters in [13] and more recently for TDMA FDMA systems by Tidestav et al. in [6]. Such a MIMO model may also be used to describe a situation, where one user terminal is equipped with several transmitter antennas. Over each antenna, a different symbol stream can be transmitted. This will increase the peak rate of that user. 2. Multiuser detection in DS CDMA systems. Here many ....

....in situations when the Doppler frequency of mobile users is not exactly known. Example 1: A fading multi user mobile radio channel. Consider a TDMA based mobile cellular communication system in which several mobile users transmit on the same frequency in the same cell and in the same time slot [38]. Receivers with multiple diversity branches detect the users simultaneously. For a case with two transmitters and two received signals obtained at di erent positions and or di ering polarizations, y 1 t y 2 t = B 11 t (q 1 ) B 12 t (q 1 ) B 21 t (q 1 ) B 22 t (q ....

....If these signals and channels can be estimated by the receiver, then the interference rejection problem becomes a multiuser detection problem. Due to several theoretical reasons which are supported by experimental results, multi user detection provides superior performance in many situations [10]. The price to be paid is an increased computational complexity. Multiuser detectors can be utilized in CDMA receivers as well as in TDMA receivers with multiple antenna elements. The aim of the work package is to investigate and develop practical and efficient multi user detectors for packet ....
