Filtered Randomized Response Technique

New Randomized Response Procedures

This article focuses on the estimation of population proportion when the study variable is sensitive in nature. Two implicit randomized response techniques are proposed where the unrelated trait can be chosen subjectively. In addition to unbiased estimation of population proportion and variance, an empirical study is conducted to inspect the relative efficiency facet of the proposed techniques....

Kim And Warde’s Mixed Randomized Response Technique For Complex Surveys

Design and Analysis of the Randomized Response Technique

About a half century ago, in 1965, Warner proposed the randomized response method as a survey technique to reduce potential bias due to nonresponse and social desirability when asking questions about sensitive behaviors and beliefs. This method asks respondents to use a randomization device, such as a coin flip, whose outcome is unobserved by the interviewer. By introducing random noise, the me...

Duobinary Partial Response Filtered SC-FDE

Abstract— Frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion significantly improves the bit error rate (BER) performance of single-carrier (SC) transmission by suppressing the channel frequencyselectivity. Partial response (PR) filtering, e.g., duobinary PR filtering, achieves higher spectral efficiency by permitting certain amount of inter-symbol interferen...

Time-Domain Selective Mapping Technique for Filtered SC-FDE

Abstract Transmit filtering, transmit equalization, precoding, or power allocation possibly increases the peak-to-average power ratio (PAPR) of transmit single-carrier (SC) signal due to change in frequency-domain spectrum. Recently, we proposed a frequency-domain based selective mapping (FD-SLM) for suppressing the increased PAPR introduced by the transmit frequency-domain equalization (Tx-FDE...
