Fuzzy recursive symbol-by-symbol detector for UMTS receivers with antenna arrays
نویسندگان
چکیده
The Maximum Likelihood Sequence Estimator (MLSE) and the Bayesian detector provide the best performance (at BER sense) under a data sequence or a symbol-by-symbol detection philosophy, respectively [1]. However, these detectors present a high computational burden and are quite unaffordable for a mobile terminal that exploits also the spatial diversity. To overcome this problem Fuzzy Logic has been applied to design a new recursive space-time detector. Simulation results show that the proposed techniques reduce the computational burden and offer similar performance to that of the optimal one.

A symbol-based fuzzy decision-making approach to evaluate the user satisfaction on services in academic digital libraries
Academic libraries play a significant role in providing core services that include research, teaching and learning. Usersatisfaction is an important indicator for evaluating the performance of library service. This paper develops a methodfor measuring the user satisfaction in a group decision-making environment. First, the performance of service isevaluated by using questionnaire survey. The sc...
متن کاملA Recursive Fuzzy System for Monitoring the Detection Performance in Digital Receivers
The paper studies the analogies and parallelism between the Bayesian approach for digital symbol sequences detection in communications problems and the techniques known as Multiple Hypotheses Tracking, which rely on fuzzy systems and inference. This comparison leads to the development of a SAM fuzzy recursive system which online estimates the performance of a blind Bayesian equalizer in a singl...
متن کاملA Symbol Synchronization Lock Detector and Snr Estimator for Qpsk, with Application to Bpsk
This paper introduces a new lock detector for symbol timing recovery PLLs in QPSK receivers operating in AWGN channels. The detector necessitates only two samples per symbol, and these samples correspond to those required by the popular Gardner[1] timing error detector. The lock detector is characterized theoretically and through simulations. It transpires that the lock detector is selfnormaliz...
متن کاملMultistage Symbol-by-symbol Bayesian Interference Cancellation for Umts-cdma Links Affected by Severe Multipath
A simple multiuser detector (MUD) is proposed for UMTSCDMA links over channels affected by severe multipath. After coherent combining and despreading, for each user a suitable “Bayesian” memoryless non-linearity gives symbolby-symbol the expected values of the transmitted data. These are employed for soft removal of inter-symbol and multipleaccess interference from the received sequences. The p...
متن کاملBayesian Optimal Data Detector for Hybrid mmWave MIMO-OFDM Systems with Low-Resolution ADCs
Hybrid analog-digital precoding architectures and low-resolution analog-to-digital converter (ADC) receivers are two solutions to reduce hardware cost and power consumption for millimeter wave (mmWave) multiple-input multiple-output (MIMO) communication systems with large antenna arrays. In this study, we consider a mmWave MIMO-OFDM receiver with a generalized hybrid architecture in which a sma...
