There is provided a transmitter device (1) for transmitting a digital input message corresponding to control data used in a control channel (for example, PUCCH, PUSCH or PRACH) through a communication channel, the transmitter device comprising a set of transmit antennas, the message m comprising a number B of bits. The transmitter device comprises:
- A binary code generator (100) configured to generate a binary code (fi) from the B bits of the message;
- A binary interleaver (102) configured to apply interleaving to the binary code, which provides an interleaved binary code (gi);
- A sequence selector (103) configured to determine a sequence (rl(ml)) of low peak-to-average power ratio vectors which depends on the message from the interleaved binary code, the sequence being associated with a sequence index,
the transmitter device (1) comprising a single-carrier or multi-carrier modulator for each transmit antenna configured to apply single-carrier or multi-carrier modulation to the combined sequence and transmit the modulated combined sequence over the communication channel using the transmit antennas.
Improved device and method for transmitting control data with low peak-to-average power ratio
