Abstract

Multicarrier modulation schemes are widely used in several digital telecommunication systems, such as Asymmetric Digital Subscriber Lines (ADSL) and Wireless Local Area Network (WLAN) based on Orthogonal Frequency Domain Multiplexing (OFDM). An estimate of the Bit-Error-Rate (BER) degradation due to non-idealities in the transceiver (e.g. nonlinear distortions in the analog front-ends, digital clipping,…) is much more complicated in a multicarrier system than in a single-carrier system due to the large number of carriers and the huge number of possible transmitted symbols. This paper proposes a method for estimating the BER of such OFDM modulation schemes in a CPU time that is two orders of magnitude smaller than a Monte-Carlo method, as confirmed by simulations on a 5 GHz IEEE 802.11 WLAN receiver front-end
