Beam Domain MIMO-OFDM Optical Wireless Communications With PAPR Reduction

Beam Domain Optical Wireless Massive MIMO Communications with Transmit Lens

We present beam domain optical wireless massive multiple-input multiple-output communications, where base station with massive transmitters communicates with a number of user terminals through transmit lens simultaneously. We focus on LED transmitters, and provide an optical channel model, where the light emitted from one LED passes through the transmit lens and generates a narrow beam. Based o...

Overall PAPR Reduction for MIMO OFDM Systems

Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems have been receiving a great attention as one of the solutions for achieving high speed, efficient, and high quality of service wireless communications. However, the main drawback of MIMO OFDM systems is high Peak to Average Power Ratio (PAPR) because of its sensitivity to the nonlinear distortions in...

PAPR Reduction Scheme with SOCP for MIMO-OFDM Systems

Combination of multiple-input multiple-output (MIMO) with orthogonal frequency division multiplexing (OFDM) has become a promising candidate for high performance wireless communications. However one major disadvantage of MIMO-OFDM systems lies in a prohibitively large peak-to-average power ratio (PAPR) of the transmitted signal on each antenna. In this paper we extend from SISO to MIMO systems ...

Mimo-ofdm Downlink Wireless System with Reduced Papr

Orthogonal Frequency Division Multiplexing (OFDM) is a multi -carrier transmission method which is most broadly used in the field of communication. One of the main drawback of this scheme is Peak to Average Power Ratio (PAPR). There are various methods introduce for the reduction of PAPR in OFDM . However these technique have major disadvantage that they reason non linear in-band deformation an...
