  1. 1. Jitter Management in Circuit Switched Voice over HSPA Networks

    University essay from

    Author : Ge Song; [2009]
    Keywords : ;

    Abstract : When a shared channel or packet switched network is used for transmission (e.g.WLAN, HSPA (Turbo-3G), LTE (4G)), it introduces variance in the delay of packets. Thisvariance is called jitter. READ MORE

  3. 2. Implementation and simulation of HSDPA functionality with ns-2

    University essay from Institutionen för systemteknik

    Author : Haichuan Jianqiu Wu Zhao; [2005]
    Keywords : Reglerteknik; UMTS; HSDPA; ns-2; EURANE; HS-DSCH; DCH; Power Consumption; FCDS; Reglerteknik;

    Abstract : Enhanced packet-data access is a trend in third generation mobile communication system. WCDMA Release 5 introduces HSDPA (High Speed Packet Data Access) with a brand new downlink transport channel HS-DSCH (High Speed Downlink Shared Channel) into 3GPP specification to provide greater capacity.

  4. 3. HSDPA System Simulation

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Sohaib Khan; Nguyen Kim Cuong; [2005]
    Keywords : High Speed Downlink Packet Access HSDPA ; Adaptive Modulation and Coding AMC ; Packet Scheduling PS ; Hybrid Automatic Retransmit reQuest ARQ ; Node B; Radio Network Controller RNC ; High-speed Downlink Shared Channel HS-DSCH ; Transmission Time Interval TTI ; Link Adaptation;

    Abstract : This thesis provides a background of the high speed downlink packet access (HSDPA) concept; a new feature which has been introduced in the Release 5 specifications of the 3GPP WCDMA/UTRA-FDD standards. In order to emphasize the theoretical analysis, a simulation of a HSDPA system shall also be performed. .. READ MORE

  5. 4. Providing Quality of Service for Streaming Applications in Evolved 3G Networks

    University essay from Institutionen för systemteknik

    Author : Jonas Eriksson; [2004]
    Keywords : Reglerteknik; UMTS; WCDMA; HSDPA; HS-DSCH; QoS; Streaming; Scheduling; Reglerteknik;

    Abstract : The third generation, 3G, mobile telephone systems are designed for multimedia communication and will offer us similar services as in our stationary computers. This will involve large traffic loads, especially in the downlink direction, i.e. from base station to terminal. READ MORE

  6. 5. High-Speed Downlink Shared Channel in Unlicensed Frequency Bands

    University essay from Institutionen för systemteknik

    Author : Kristina Zetterberg; [2004]
    Keywords : Reglerteknik; HSDPA; HS-DSCH; unlicensed frequency bands; UMTS; WCDMA; Reglerteknik;

    Abstract : In the standardized air interface for third generation mobile communication systems, WCDMA release 5, a concept called High Speed Downlink Packet Access (HSDPA) is introduced. HSDPA enables faster transmissions from base stations to mobile users by using a shared, high-capacity channel called the High-Speed Downlink Shared Channel (HS-DSCH) that is designed for best effort services.
