Abstract: PURPOSE: An IFFT(Inverse Fast Fourier Transform) apparatus for subscriber equipment in a cable network which shares uplink channel resources is provided to control an increase in system complexity by maintaining backward compatibility against an existing DOCSIS(Data Over Cable Service Interface Specification) MAC(Medium Access Control). CONSTITUTION: A channel encoding part(210) corrects errors caused by all kinds of noises by inserting some redundant bits into a digital transmission signal. A mapping part(220) matches an output signal of the channel encoding part with modulated signals like 256(Quadrature Amplitude Modulation) and 1024QAM for channel characteristics of a transmission media. A variable IFFT apparatus(230) performs IFFT. A CP(Cyclic Prefix) insertion part(240) inserts a CP into a guard interval section in order to prevent interference between channels. A DAC(Digital-to-Analog convert)(250) changes a discrete digital signal to a successive analog signal. A RF transmission part(260) transmits an amplified signal to a cable network by upconverting a DAC output using a desired frequency channel.

Abstract: PURPOSE: A method for allocating data and a pilot in accordance with physical layer channel bonding is provided to stably compensate for a channel of a guard band. CONSTITUTION: It is determined whether transmission data exceeds one channel capacity(S410). Only a single channel is used when the transmission data does not exceed one channel capacity(S420).
