RECEIVER FOR RECEIVING DATA IN A BROADCAST SYSTEM USING REDUNDANCY DATA |
摘要 |
A receiver for receiving data in a broadcast system includes a broadcast receiver that receives, via the broadcast system, a receiver input data stream including plural channel symbols represented by constellation points in a constellation diagram. A demodulator demodulates the channel symbols into codewords and a decoder decodes the codewords into output data words. A broadband receiver obtains redundancy data via a broadband system, the redundancy data for a channel symbol including one or more least robust bits of the channel symbol or a constellation subset identifier indicating a subset of constellation points including the constellation point representing the channel symbol. The demodulator and/or the decoder is configured to use the redundancy data to demodulate the respective channel symbol and to decode the respective codeword, respectively. |
