A novel OFDM PAPR reduction scheme by exploiting frequency guard band (FGB) is proposed and experimentally demonstrated. Effective mitigation of nonlinear impairments is validated and BER improvement of 2.6 dB is achieved over 50-km fiber transmission without sacrificing data rate. OCIS codes: (060.4510) Optical communications; (060.4080) Modulation

The prevailing labor market models assume that minimum wages do not affect the labor supply schedule. We challenge this view in this paper by showing experimentally that minimum wages have significant and lasting effects on subjects’ reservation wages. The temporary introduction of a minimum wage leads to a rise in subjects’ reservation wages which persists even after the minimum wage has been ...

This paper studies resource reservation mechanisms that can be incorporated into distributed multi–path Quality– of–Service (QoS) routing algorithms. Three resource reservation schemes, the forward reservation scheme, the backward reservation scheme and the hybrid reservation scheme, are investigated. Simulations are carried out to compare the performance of the protocols and to study the impac...

In terms of delivery of compressed videos, two service categories are frequently considered, namely, deterministic and statistic. It is a general belief that the statistic service can achieve more efficient bandwidth utilization than the deterministic one due to its statistically multiplexing streams. In this paper, we, however, investigate the possibility of applying the multiplexing principle...

We have studied 131 patients (over 12 y/o) for hearing aids evaluation by the Noise Impulse Hearing Test using the fitting system TR 60 and have compared the test results with the subjective estimation of the patients wearing hearing aids. The judgement for selection of hearing aids by TR 60 is made by measuring most comfortable level (MCL) on the condition of wearing hearing aids, using narrow...

Do reported reservation wages correspond to the concept of reservation wages that economists have? Using panel data on British unemployed I calculate reservation wages from a search model and compare these with reported reservation wages. It is shown that men’s reported reservation wages are greater than what the model predicts, and that for women there is hardly a relation between the two vari...
