A PAPR reduction scheme based on a new spreading code in optical direct detection OFDM system

A PAPR reduction scheme based on a new spreading code in optical direct detection OFDM system In this paper, we propose and experimentally demonstrate a peak-to-average power ratio (PAPR) reduction scheme based on a new spreading code in direct detection optical orthogonal frequency division multiplexing (OFDM) system. The new spreading code with low cross correlation and high auto-correlation can support $$2N+1$$ 2 N + 1 users. Thus, $$2N+1$$ 2 N + 1 users or data symbols can be transmitted over only N subcarriers. The experimental results show that, after transmission over 70 km single-mode fiber, at the bit error rate of $$10^{-3}$$ 10 - 3 , with fiber launch power of 2.75 dBm, the receiver sensitivity can be improved 2.1 dB by using the proposed scheme based on new spreading code.

Abstract

In this paper, we propose and experimentally demonstrate a peak-to-average power ratio (PAPR) reduction scheme based on a new spreading code in direct detection optical orthogonal frequency division multiplexing (OFDM) system. The new spreading code with low cross correlation and high auto-correlation can support $$2N+1$$ 2 N + 1 users. Thus, $$2N+1$$ 2 N + 1 users or data symbols can be transmitted over only N subcarriers. The experimental results show that, after transmission over 70 km single-mode fiber, at the bit error rate of $$10^{-3}$$ 10 - 3 , with fiber launch power of 2.75 dBm, the receiver sensitivity can be improved 2.1 dB by using the proposed scheme based on new spreading code. The PAPR can be reduced about 4.6 dB, compared with the original OFDM signal at a complementary cumulative distribution function of $$10^{-4}$$ 10 - 4 .
