Modi ed Active Constellation Extension for PAPR Reduction of Space-Frequency Block Coded OFDM Systems
In this paper, the Active Constellation Extension (ACE) technique is applied to Space Frequency Block Coded (SFBC) OFDM systems to reduce the Peak to Average Power Ratio (PAPR). For the extension of this technique to SFBC systems, it will be shown that the space frequency coded signals are the combination of several subframes and that the ACE method may be applied to these subframes. Using this...
متن کاملA study on LDPC coded hybrid-ARQ using spatially multiplexed MIMO-OFDM
In this paper, we consider the Type-II Hybrid ARQ schemes with the LDPC codes having the rate of 0.5 through MIMO-OFDM Spatial Multiplexing (SM) schemes for high speed and high throughput transmission. MMSE nulling and MLD are used for the signal separation and detection method in SM. We also have used the channel estimation per subcarrier with MMSE criterion. The uncoded Hybrid ARQ schemes wit...
متن کاملUsing WPT as a New Method Instead of FFT for Improving the Performance of OFDM Modulation
Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...
متن کاملIncreasing the Performance of OFDM Systems by PAPR Reduction in PTS Technique using Election Optimization Algorithm
Orthogonal Frequency Division Multiplexing (OFDM) is a useful technology in wireless communications that provides high-rate data transmission in multipath fading channels. The advantages of OFDM systems are the high spectral efficiency and strong resistance to frequency selective fading. In OFDM systems, a large number of sub-carriers are used to modulate the symbols causing the time-domain OFD...
متن کاملH-ARQ Techniques for Wireless Systems with Punctured Non-Binary LDPC as FEC Code
This paper presents the H-ARQ techniques comparison for OFDM systems with a new family of non-binary LDPC codes which has been developed within the EU FP7 DAVINCI project. The punctured NB-LDPC codes have been used in a simulated model of the transmission system. The link level performance has been evaluated in terms of spectral efficiency, codeword error rate and average number of retransmissi...
