چکیده

-Recently we proposed the long range prediction algorithm for fast fading channels. This method provides the enabling technology for adaptive transmission techniques such as adaptive coding, adaptive power control, etc. In this paper, we used actual field measurements to validate the long range prediction method and its utilization in adaptive power control.

Long Range Prediction Makes Adaptive Modulation Feasible for Realistic Mobile Radio Channels

-Adaptive transmission techniques, such as adaptive modulation and coding, adaptive power control, adaptive transmitter diversity, etc., depend on the transmitter's ability to predict future behavior of the channel. Recently, we proposed a reliable long-range prediction algorithm for rapidly time variant fading channels. In this paper, we analyze the statistical behavior of the errors generated...

Long Range Prediction of Fading Signals: Enabling Adaptive Transmission for Mobile Radio Channels

Recently it was proposed to adapt several transmission methods, including modulation, power control, channel coding and antenna diversity to rapidly time variant fading channel conditions. Prediction of the channel coefficients several tens-to-hundreds of symbols ahead is essential to realize these methods in practice. We describe a novel adaptive long range fading channel prediction algorithm ...

Reliable Adaptive Modulation Using Long-Range Prediction at a Different Carrier Frequency

– For fast vehicle speeds, reliable adaptive transmission requires prediction of future channel state information (CSI) since the channel conditions are rapidly time-variant. In this paper, we propose to use past channel observations of one carrier to predict future CSI and perform adaptive modulation for another correlated carrier. Statistical model of the prediction error that depends on the ...

A Physical Model for Wireless Channels to Understand and Test Long Range Prediction of Flat Fading

Algorithms [1 7] that predict the wireless channel for up to a few wavelengths cannot be adequately tested with stationary models, such as the Jakes model [8]. Moreover, ray-tracing or finite difference time domain (FDTD) methods do not provide insights into the relationship between the reflector configurations and the performance of the long-range prediction. A novel model is required to: (1) ...

Adaptive modulation using outdated samples of another fading channel

Adaptive transmission techniques, such as adaptive modulation and coding, adaptive power control, adaptive transmitter antenna diversity, etc., generally require precise channel estimation and channel state information (CSI) feedback. For fast vehicle speeds, reliable adaptive transmission also requires prediction of future CSI since the channel conditions are rapidly time-variant. In this pape...
