Blind Carrier Frequency Offset Estimation in SISO, MIMO, and Multiuser OFDM Systems
White Papers Relying on a kurtosis-type criterion, a low-complexity blind carrier frequency offset (CFO) estimator is developed for orthogonal frequency-division multiplexing (OFDM) systems. The paper demonstrates analytically how identifiability and...

Blind Separation of Speech With a Switched Sparsity and Temporal Criteria
White Papers A Blind Signal Separation algorithm (SCAtemp) that exploits both the sparse time-frequency representation and temporal structure of speech is proposed. SCAtemp compares each speech signal's adherence to the sparsity and temporal criteria, before...

Blind and Semiblind Spatio-Temporal Diversity for OFDM Systems
White Papers A blind method is firstly proposed for the maximization of the temporal Signal to Noise plus Interference Ratio (SNIR) in frequency selective channels exploiting the temporal redundancy introduced by the Cyclic Prefix (CP).

Generalized 8-PSK for Totally Blind Channel Estimation in OFDM
White Papers Most blind channel estimation approaches are based on higher order statistics and converge slowly, making them unsuitable for mobile environments. The concept of totally blind channel estimation makes pilots completely unnecessary and even works in...

A Comparison of Blind Channel Estimation Schemes for OFDM in Fading Channels
White Papers This paper brings together three recently proposed blind detection schemes which are specific to Orthogonal Frequency Division Multiplexing (OFDM) systems. The aim is to study the performance of these schemes in fading channels and thus give a...

Minimum-Output-Energy Method for Blind Equalization of OFDM and Systems With Sufficient or Insufficient Cyclic Prefix
White Papers In this paper, a new blind equalization method is proposed for systems with cyclic prefix such as OFDM. With constrained Minimum-Output-Energy (MOE) optimization, a bank of equalizers can be derived without the help of FFT/IFFT.

A Blind Frequency Offset Estimator for OFDM/OQAM Systems
White Papers A new blind carrier frequency estimator is introduced herein for OFDM- /OQAM systems by exploiting the non-circularity of the received signal. Like other OFDM-like systems, OFDM/OQAM systems are very sensitive to carrier frequency offset.

Peak-to-Average Power Ratio Reduction in OFDM With Blind Selected Pilot Tone Modulation
White Papers Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. However, the price paid for the high spectral efficiency is low power...
