Patent Searching and Data


Title:
多入力多出力ターボ受信方法及びその受信機
Document Type and Number:
Japanese Patent JP4215148
Kind Code:
B2
Abstract:

To improve an error rate characteristic when there is a big difference between received power of signals from respective transmitters.

Received energy per information bit of a received signal from each transmitter is calculated (S2), and equalization and decoding processing is applied to the received signal from the receiver in the order of large received energy. That is, for example, only a received signal corresponding to a transmitter with large received energy in the previous prior information is used to perform equalization processing, and equalization and decoding processing is also applied to a received signal from a transmitter with small received energy according as the repetition of equalization and decoding is increased.
