Patent ID: 8737435

Claim:
An encoder comprising: a precoder for encoding an input information object according to a preset encoding scheme and storing the encoded information object in a precoder buffer; a sample number and address generation unit for generating a sample number of each sample and an address, which corresponds to each bit of each sample and the address of the precoder buffer; a multiplexer for selecting a bit of the precoder buffer corresponding to the address generated by the sample number and address generation module; a sampling buffer for storing a bit of each sample output from the multiplexer; a control packet generation module for generating a control packet including information on the sample number generated by the sample number/address generation module; a packet assembling unit for assembling the sample stored in the sampling buffer with the control packet generated by the control data generation module; and a modulation module comprising: a spectrum correction unit for correcting a spectrum of the packet output from the packet assembling unit, a modulator for modulating the packet from the spectrum correction unit into a sound signal according to at least one preset modulation scheme, and a synchronization sequence addition unit for adding a synchronous signal to the sound signal output from the modulator in a time domain.
