Title:
SPACE-TIME CODING/DECODING METHOD FOR FREQUENCY SELECTIVE FADING CHANNEL
Document Type and Number:
WIPO Patent Application WO/2004/002036
Kind Code:
A1
Abstract:
The present invention relates to a space-time coding/decoding method for frequency selective fading channel, including: a coder uses space-time individual block orthogonal coding method and uses two individual data blocks of one slot in the input data as processing unit to encode two data vectors, and two generated diversity signals are transmitted simultaneously corresponding to two diversity antennas; receiving terminal ignores the mutual interference between the two diversity signals resulting from nonorthogonality; when only the interference of multipath and multiuser between the two diversity signals is considered, joint detection is performed to obtain the result of decoding; with the result of joint detection the interference can be cancellated, and the intereference between the two diversity signals can be eliminated, then back to the prior step and iterate decoding is excuted,the number of times of iteration can be preset. The present invention adopts individual data block as coding/decoding processing unit and adopts iteration method of joint detection together with interference cancellation to perform decoding. This invention provides a simple and effective solution to the application of space-time code in frequency selective fading channel.
