Iterative amplitude reconstruction of clipped OFDM signals with optimum equalisation

open access: yes, 2018
A technique called iterative amplitude reconstruction (IAR) is proposed for recovering the clipped orthogonal frequency-division multiplexing (OFDM) signals, where optimum equaliser tap coefficients are obtained under the MMSE criterion. The proposed IAR

Subblocks Set Design Aided Orthogonal Frequency Division Multiplexing With All Index Modulation

open access: yesIEEE Access, 2019
In recent years, OFDM with index modulation (OFDM-IM) has become a potential technique due to its improvement of diversity gain. In typical OFDM-IM schemes, incoming information bits are divided into two parts, symbols bits, and index bits.

Sample-Spaced and Fractionally-Spaced CIR Estimation Aided Decision Directed Channel Estimation for OFDM and MC-CDMA

open access: yes, 2005
The achievable performance of decision-directed channel estimation (DDCE) is analysed in the context of both OFDM and MC CDMA systems. Two different estimation methods suitable for both OFDM and MC-CDMA systems are considered, which employ sample-spaced (
