    Influence of Interleaving to OFDM-CDMA PAPR and to Efficiency of Power Amplifiers Driven with OFDM-CDMA signals

  • Original language description

    In this contribution, we present and discuss how the interleaving principle can be used in OFDM, MC-CDMA and MC-DS-CDMA systems in order to reduce the PAPR. Moreover, we analyze the improvement of power amplifier efficiency gained by the PAPR reduction using several selected methods employing interleaving principle. The methods under consideration are Multiple Signal Representation (MSR) for OFDM and frequency interleaving (random or optimized) for MC-CDMA and MC-DS-CDMA.

    Vliv prokládání na PAPR u OFDM-CDMA a na účinnost zesilovačů buzených signály OFDM-CDMA

  • Czech description

    V tomto článku je prezentována možnost redukce PAPR u OFDM, MC-CDMA a MC-DS-CDMA pomocí metod založených na prokládání. Navíc je analyzováno zlepšení účinnosti výkonového zesilovače vlivem redukce PAPR. Středem pozornosti jsou metody MSR pro OFDM a prokládání ve frekvenční oblasti pro OFDM-CDMA systémy.
