—We analyze the throughout achievable in transmission over block-fading channels when the instantaneous channel state information (CSI) is not available at the transmitter. Assuming operation with incremental redundancy hybrid ARQ (HARQ), we propose to adapt the transmissions rates using the outdated CSI, i.e., the one experienced by the receiver in the(More)
The original idea of mobile IP (MIP) is to provide mobile users the ability to access the Internet anywhere, with an identical IP address. With rapid changes in both technology and the communication environment, wide bandwidth and low cost wireless LAN (WLAN) have emerged as a competitive choice not only for wireless high speed Internet access but also for(More)
High Peak-to-Average Power Ratio (PAPR) is one of the main drawbacks that may limit practical applications of Orthogonal Frequency Division Multiplexing (OFDM) System. Based on the well known Selective Mapping (SLM) method of PAPR reduction, in this paper, we propose a new phase sequence generation technique from Condex matrix that can achieve better PAPR(More)
The Mobile IP (MIP) enables a mobile user to access the Internet anywhere with an identical IP address. However, in order to support mobility with quality of service (QoS), MIP can be inefficient for both data and time sensitive services such as voice-over-IP (VoIP). Broadband accessed network server IP mobility architecture facilitates WLAN IP mobility(More)
The integration of wireless local area networks (WLANs) and the high speed wide area network (WAN) using 'always on' broadband access that could provide an efficient and cost effective inter-WLAN mobility management requires the current WLAN internetworking protocol enhanced. The Inter Access Point Protocol (IAPP) defines methods for access point(More)
