چکیده

An adaptive transmission protocol is described and evaluated for use in wireless communication networks that employ dynamic spectrum assignment. The protocol interacts with a spectrum assignment system to select the modulation format and symbol transmission rate for each session. The power is adjusted during the initial part of each session, and code-rate adaptation is employed to compensate for changes in propagation loss that occur during the session.

An Adaptive Opportunistic Transmission for Unlicensed Spectrum Sharing in Heterogeneous Networks

Efficient utilization of spectrum resources is a fundamental issue of wireless communications due to its scarcity. To improve the efficiency of spectrum utilization, the spectrum sharing for unlicensed bands is being regarded as one of key technologies in the next generation wireless networks. A number of schemes such as Listen-Before-Talk(LBT) and carrier sensor adaptive transmission (CSAT) ha...

Adaptive Modulation in OSA-based Cognitive Radio Networks

Opportunistic spectrum access is based on channel state information and can lead to important performance improvements for the underlying communication systems. On the other hand adaptive modulation is also based on channel state information and can achieve increased transmission rates in fading channels. In this work we propose the combination of adaptive modulation with opportunistic spectrum...

A Demonstration of Adaptive Spectrum Sensing and Interference Suppressed Opportunistic Secondary Transmission

We consider spectrum sensing and Non-Contiguous OFDM (NC-OFDM) with interference avoidance to facilitate opportunistic secondary transmission. In this application protecting an incumbent primary user of the spectrum from secondary emissions is a key design requirement. We present an adaptive sense-and-carefully-transmit system which integrates a spectrum sensing module with an NC-OFDM transmitt...

Adaptive Signal Detection in Auto-Regressive Interference with Gaussian Spectrum

A detector for the case of a radar target with known Doppler and unknown complex amplitude in complex Gaussian noise with unknown parameters has been derived. The detector assumes that the noise is an Auto-Regressive (AR) process with Gaussian autocorrelation function which is a suitable model for ground clutter in most scenarios involving airborne radars. The detector estimates the unknown...
