A spectrum sharing method based on ATM
In recent years, the number of portable mobile terminal users is increasing with improvement of the wireless communication environment. In addition, mobile multimedia services also bring the increase of wireless traffic and lack of
spectrum resources. As a technique for efficient spectrum use, spectrum sharing receives much attention. It dynamically assigns a spectrum channel from a larger area network such as WiMAX to smaller area networks such as WiFi-based wireless LANs and achieves to increase the total wireless communication capacity of this area. In a case where all providers are cooperative, the spectrum sharing can be realized easily and improve user throughput in average. In another case where providers are not
cooperative, some spectrum trading methods based on auction theory had been proposed.

Bit Error Rate analysis of an Extended Receiver for Rectangular PAM.
The performance of a digital communication system in the presence of additive white Gaussian noise (AWGN) can be assessed by the measurement of the bit error rate (BER). The Simulink model provided is a rectangular polar pulse amplitude modulation (PAM) baseband system with an AWGN channel and an extended sample and hold receiver with a low pass filter.
An extended receiver has an odd number of sample and hold circuits. What remains to be answered is if such a receiver would provide a more desirable BER than that of a simple S/H receiver.

A-Novel-Variable-Step-Size-NLMS-Algorithm-and-Its
By building the generalized Sigmoid function relationship between normalized step-size and the power of error signal,
a novel variable step-size NLMS algorithm is proposed. It is proved that the step-size of NPVSS-NLMS changes as
the new algorithm does when A=σv
-m and B=2. The physical meanings of the parameters in this algorithm are
explored. The theoretical analysis illustrate that this algorithm combine the virtues of NPVSS-NLMS and Sigmoid
function, and it leads to faster convergence rate and lower final misalignment. The computer simulation results
support the theoretical analysis.
