Adaptive MLSE equalization forms for wireless communicationsinimize the amount of channel prediction. The first form developed, referred to as the “direct form,” uses a standard Euclidean distance metric. A second, novel form, referred to as the “partial Ungerboeck form,” provides a lower complexity realization than the “direct form. ”作者: Ostrich 時(shí)間: 2025-3-28 07:33

An Evaluation Point Culling Algorithm for Radio Propagation Simulation based on the Imaging Methodg method, which is one of the ray tracing methods. First, the probability that propagation paths exist at evaluation points within second-order reflection is shown. The result shows that the probability is less than a few percents. Therefore, it appears that the computation time can be reduced by el作者: 組裝 時(shí)間: 2025-3-30 10:24

On the Use of Signal-to-Noise Ratio Estimation for Establishing Hidden Markov Modelsrated. A dynamic channel model is first found by monitoring the receiver input signal-to-noise ratio (SNR). Each channel state is then embedded with a binary error Fritchman model. From the Markov model, system performance parameters, such as the bit-error-rate (BER), can be determined directly.作者: 換話題 時(shí)間: 2025-3-31 04:25
