In this letter, we analyze the inter-carrier-interference (ICI) caused by Doppler spreading in an orthogonal frequency-division multiplexing system wh...

In this letter, two modified nonlinear least square (NLS) estimators for carrier frequency offset (CFO) in orthogonal frequency-division multiplexing...

The proportional delay differentiation model provides consistent packet delay differentiation between classes of service. The waiting time priority (W...

Current admission controls seeking to optimize network utilization create a bias against wideband calls. This paper proposes a BNP (buffer without pre...

Due to the special requirements of the mobile code system, in 2000, Shieh et al. proposed some multisignature schemes based on a new digital signature...
