    Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

  2. 2. Crest Factor Reduction using High Level Synthesis

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Hassan Mahmood; [2017]
    Keywords : Peak to average power ratio; Crest factor; Peak cancellation crest factor reduction; High level synthesis; Design space exploration; Object oriented programming; SystemC; Skillnad mellan maximal effekt och medeleffekt; Toppfaktor; Algoritmen peak cancellation; Högnivåsyntes; SystemC; Undersökningen av designalternativ; Objektorienterad programmering;

    Abstract : Modern wireless mobile communication technology has made noticeable improvements from the technologies in the past but is still plagued by poor power efficiency of power amplifiers found in today’s base stations. One of the factors that affect the power efficiency adversely comes from modern modulation techniques like orthogonal frequency division multiplexing which result in signals with high peak to average power ratio, also known as the crest factor.

  3. 3. An efficient Hardware implementation of the Peak Cancellation Crest Factor Reduction Algorithm

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Matteo Bernini; [2016]
    Keywords : CFR; PC-CFR; PAPR Reduction; OFDM; CFR; PC-CFR; PAPR Reduction; OFDM;

    Abstract : An important component of the cost of a radio base station comes from to the Power Amplifier driving the array of antennas. The cost can be split in Capital and Operational expenditure, due to the high design and realization costs and low energy efficiency of the Power Amplifier respectively. READ MORE
