DIFFERENTIAL MULTIPLE-NORM TRANSMIT DIVERSITY WITH FORWARD ERROR CORRECTION AND RELATED DIVERSITY RECEPTION

摘要

The present invention realizes that difference sends diversity and relevant diversity reception scheme, and its transmission expands to multistage symbol constellation.Up to now, a group of transmission bits is divided into first son and divides into groups to send the position and the second son grouping transmission position.Then, the first son grouping sends position mapped (14) sends the difference transmission diversity encoding scheme that comes from orthogonal design of position to the first son grouping that is used to encode constellation point.Then, in differential coding constellation point (32,34,36,40) afterwards, the transmission symbolic vector length that the second son grouping that is used to encode is sent the position is calibrated (38).Therefore, the present invention has overcome element length that the difference of understanding in advance that comes from orthogonal design sends diversity scheme and has required the restriction of being implied.
