no. 1 approach

[0041] See figure 1 , Which is a block diagram of the multi-service transmission system 10 compatible with single antenna reception and multi-antenna reception according to the present invention. The transmission system 10 compatible with a single-antenna receiver and a multi-antenna receiver is applied to a broadcast channel.

[0042] The transmission system 10 compatible with a single-antenna receiver and a multi-antenna receiver includes a transmitter 11 and a receiver 12, wherein the transmitter 11 adopts a multi-antenna architecture for transmitting two different service data. The two different service data are the service MISO service (Multiple-InputSingle-Outiput, hereinafter referred to as MISO service) for simultaneous reception and decoding by single-antenna receiver and multi-antenna receiver, and the service only for reception and decoding by multi-antenna receiver Service (hereinafter referred to as MIMO service). The receiver 12 includes a single-antenna receiver 1...

Abstract

The invention provides a broadcasting channel data transmitting receiving method executed by a multi-business transmission system compatible with single-antenna receiving and multi-antenna receiving. The broadcasting channel data transmitting receiving method comprises steps that a physical layer symbol sequence is grouped according to MISO business, service quality demands required by MIMO business, and multi-antenna constellation graph used by a transmitting end, and every physical layer symbol group is segmented at a bit level, and then MISO business sub-channels and MIMO business sub-channels at the bit level are acquired; the transmission data bits of the MISO business and the transmission data bits of the MIMO business are disposed in the corresponding bit layer sub-channels in a filled manner, and bit vectors filled with the business data are mapped in the constellation graph, and are transmitted by baseband equivalent channels; the MISO business sub-channels in received signals are decoded, and the MISO business data bits are acquired after the decoding, and then an MIMO receiving device is used to decode the MIMO business by taking the decoded MISO business data bits as apriori information.
