    Sammanfattning : Superconducting digital technology based on Rapid Single Flux Quantum logic (RSFQ) is a digital technology characterized by high speed, low power consumption and low operational temperatures. RSFQ is attractive for many applications and in particular for high frequency Digital Signal Processing (DSP) and for digital control of mK devices like superconducting qubits. LÄS MER

  3. 2. Superconductor Digital Signal Processor

    Författare :Irina Kataeva; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rapid Single Flux Quantum logic RSFQ ; multiuser detector; VHDL; Multiply-Accumulate Unit; Successive Interference Canceller;

    Sammanfattning : Superconductor digital technology based on Rapid Single Flux Quantum logic (RSFQ) offers more than 50 times gain in speed and more than 100 reduction in power consumption over mainstream CMOS devices. However, the necessity of cooling down to 4 K and modest degree of integration density currently available mean that employing RSFQ is reasonable only for the tasks that are impossible or ineffective to implement in CMOS technology.

  7. 5. Aspects of Fixed-point Implementation of Multiuser Detctors in WCDMA

    Författare :Hongxia Zhao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Wideband code-division multiple-access (WCDMA) has been selected as the radio technique standard for the 3G mobile communication systems. However, it is well known that the conventional single-user detector, which is commonly used in CDMA systems, suffers from multiple-access interference (MAI). LÄS MER
