Title:
RADIO TRANSMITTER AND RECEIVER FOR ULTRA-NARROW BAND TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2016/122044
Kind Code:
A1
Abstract:
The present invention relates to a radio transmitter and receiver for ultra-narrow band transmission. A radio transmitter for ultra-narrow band transmission according to an embodiment of the present invention comprises: a CRC encoder for performing CRC encoding of a protocol data unit; a scrambler for scrambling the CRC encoded protocol data unit; a convolutional encoder for performing convolutional encoding of the CRC encoded and scrambled protocol data unit; a channel interleaver for performing channel interleaving of a signal received from the convolutional encoder; a symbol mapping unit for mapping a signal received from the channel interleaver to a particular symbol; an RRC filter for limiting the band of a signal to an ultra-narrow band; and an interpolation filter unit for performing interpolation.
