Title:
TURBO DETECTION METHOD AND DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/015592
Kind Code:
A1
Abstract:
Disclosed are a Turbo detection method and a device thereof. The method is realized by executing the following operations in an iteration mode: receiving a signal vector y and second feedback information, and acquiring equivalent frequency-domain channel estimation matrices Η of various channels receiving the signal vector; according to the second feedback information and the equivalent frequency-domain channel estimation matrices Η, demodulating the signal vector y to obtain a log likelihood ratio λ; conducting descrambling, coding block cascading and rate de-matching on the log likelihood ratio λ and then obtaining prior information, and decoding the prior information based on the maximum a posteriori rule, so as to obtain external information γ; determining whether the reliability of the prior information and the external information γ meets requirements, and setting first feedback information as 0 if the reliability of the prior information and the external information γ does not meet the requirements; and conducting rate matching, coding block cascading and scrambling processing on the first feedback information, so as to obtain second feedback information, so that the operation complexity and processing time delay of Turbo detection can be reduced.
