- 摘要：
- Method and apparatus for preparing a message stream of symbols for wireless transmission by pre-coding in through convolution with a characteristic "signature" of predetermined symbols identifying a particular user of the message system. The time duration of the signature should exceed the inter-symbol interval of the message stream in order to reduce the likelihood of error caused by fading in the transmission channel.
