The Pilot Alignment Pattern Design in OFDM Systems
نویسندگان
چکیده
In this paper, we propose optimal pilot pattern of downlink OFDM (Orthogonal Frequency Division Multiplexing) communication system. Current pilot patterns in OFDM system are evaluated with new criteria, new pilot pattern and “distance” filter which has small computational burden is suggested. The combination of suggested cell pilot pattern and “distance” filter provides better performance than LMMSE estimation which implements time-frequency correlation about some patterns.

Proposed Pilot Pattern Methods for Improvement DVB-T System Performance
Recently, orthogonal frequency division multiplexing (OFDM) has been extensively used in communications systems to resist channel impairments in frequency selective channels. OFDM is a multicarrier transmission technology in wireless environment that use a large number of orthogonal subcarriers to transmit information. OFDM is one of the most important blocks in digital video broadcast-terrestr...
متن کاملDesign of Pilot Pattern for Channel Estimation in OFDM Systems
Channel estimation is necessary for coherent detection in orthogonal frequency division multiplexing (OFDM) receivers. For accurate estimation, known pilot symbols are sent with data symbols at the transmitter. In general, these pilot symbols are placed with a regular pattern in two-dimensional (2-D) time-frequency grid. In a static additive Gaussian noisy channel, the channel estimation perfor...
متن کاملEstimation in OFDM Based Cognitive Radio Systems BER Analysis for Fourier and Wavelet Transform Process
In this correspondence, sparse channel estimation is first introduced in orthogonal frequency-division multiplexing (OFDM)-based cognitive radio systems. Based on the results of spectrum sensing, the pilot design is studied by minimizing the coherence of the dictionary matrix used for sparse recovery. Then, it is formulated as an optimal column selection problem where a table is generated and t...
متن کاملIssues on Broadband Wireless Communication Systems: Channel Estimation, Frequency Synchronization and Space-Time-Frequency Coding
“Faster, higher, stronger”– the Olympic motto is being pursued and practised in the design of broadband wireless communication systems. Motivated by the huge demands for fast and reliable communications over wireless channels, broadband communication systems are required to provide faster (lowcomplexity) data processing, higher data throughput and stronger (lower error rate) performance. In pra...
متن کاملMinimization of PAPR in MIMO-OFDM Systems by Tone Reservation Techniques and Pilot Tones
In this paper a method that mixes tone reservation (TR) techniques and phase information of the pilot tones to efficiently reduce the peak to average power ratio (PAPR) of the multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) signals is presented. First, we utilize convex optimization techniques to design dummy symbols to unused or reserved set of subcarrie...
