  1. 6. Receiver Front-end Design for WiMAX/LTE in 90 nm CMOS

    University essay from

    Author : Hans Rabén; [2009]
    Keywords : ;

    Abstract : The development of wireless communication systems into multi-standard radio architectures that can process a multitude of frequency bands and modulation schemes has lead to a growing demand for wideband receiver front-ends. To allow for portability and low cost, these new architectures also need to be low power, compact size integrated circuits with a higher degree of components integrated on chip. READ MORE

  3. 7. Scheduling Algorithms and QoS in HSDPA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Javed Iqbal; Basit Mustafa; [2009]
    Keywords : HSDPA; QoS; Scheduling Algorithms;

    Abstract : High Speed Downlink Packet Access (HSDPA) is the extension to the Universal Mobile Telecommunication System (UMTS). HSDPA allows for higher data rates due to new adaptive Modulation and Coding (AMC) techniques, Hybrid Automatic Repeat reQuest (H-ARQ) and fast scheduling algorithm. READ MORE
