Low-Complexity Receiver for HACO-OFDM in Optical Wireless Communications

چکیده
In this letter, a low-complexity receiver (Rx) is proposed for hybrid asymmetrically clipped optical orthogonal frequency division multiplexing (HACO-OFDM). Owing to the special time-domain property of HACO-OFDM, overlaid OFDM (ACO-OFDM) and pulse-amplitude-modulated discrete multitoned (PAM-DMT) signals can be distinguished in time domain reduce its computational complexity. Besides, near-optimal power allocation further applied optimize system performance. Theoretical analysis simulation results demonstrate that, Rx achieve nearly same bit error rate (BER) performance as BER-optimal iterative but with an effective complexity reduction, thus demonstrating application potential high-speed communication systems.

Low-complexity receiver for OFDM in doubly-selective channels
Orthogonal frequency division multiplexing (OFDM) systems may experience significant inter-carrier interference (ICI) when used in timeand frequency-selective, or doubly-selective, channels. In such cases, the classical symbol estimation schemes, e.g., minimum mean-squared error (MMSE) and zero-forcing (ZF) estimation, require matrix inversion that is prohibitively complex for large symbol leng...
متن کاملA low complexity antenna diversity receiver for OFDM based systems
A low complexity antenna diversity architecture with a new combining technique suitable for Orthogonal Frequency Division (OFDM) based systems is introduced in this paper. For a two branch antenna diversity, this structure requires only one FFT at the receiver and allows optimum maximum ratio combining. For systems with a higher number of antennas, the number of required FFTs when using such te...

In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce the PAPR.The coded bits at the input of OFDM modulator are separated into two groups of the Most Significant Bits (MSB) and the LeastSignificant Bits (LSB). The bits are mappe...
متن کاملOptical wireless communications utilizing a dicode PPM PIN-BJT receiver
Original results are presented for an optical wireless system employing dicode pulse position modulation (DiPPM) and a PINBJT receiver. When operating at 0.85 m and a bit rate of 10 Mb/s, a sensitivity of 51 dBm (Pe 10 ) is achieved, which represents a 10.3-dB improvement, as compared to an equivalent PCM system. The work also demonstrates that DiPPM achieves comparable sensitivities to those o...
