Provided are a human body communication apparatus for non-contact communications using a frequency-selective baseband and a human body communication method for non-contact communications in the same. The human body communication apparatus may be useful to perform stable communications between users by reducing interference induced from other communication apparatuses without affecting interference between the users since data are transmitted/received between communication apparatuses adjacent to a human body by spreading and despreading the data using only spreading codes of a limited frequency band (frequency-selective baseband) in which an inductive electromagnetic field formed by an antenna shows the most effective characteristics.

Provided is an apparatus for generating a ranging binary code sequence at a high-speed, and a method thereof. The apparatus includes: an initial register value generator for generating initial register values of minimum valid ranging codes; a storage for storing the generated initial register values of the valid ranging codes(≦K, where K is the ranging value transmitted by base station); a binary code sequence generator for generating a binary code sequence of a corresponding ranging code; and a procedure for incrementally updating the initial register values as receiving the new ranging code from base station.

Provided is an intra-body communication system which enables high-speed data transmission while limiting the frequency band of a signal being transmitted through a human body to a frequency range (e.g., 30-40 MHz) where the human body can maintain waveguide properties and enables stable intra-body communication by minimizing interference by other users or other electronic devices. A transceiver of the intra-body communication system for high-speed data transmission includes: a source encoder for encoding source information to digital transmission data; a channel error prevention unit for inserting a redundant bit to the encoded transmission data; a mapper for symbolizing the transmission data outputted from the channel error prevention unit; a spreader for performing spread spectrum on the symbolized transmission data in a frequency domain; and a pulse shaping and modulator for generating a baseband signal with a band range limited to a frequency range where the human body retains waveguide properties.

Disclosed is an apparatus for performing both FHT (Fast Hadamard Transform) and FFT (Fast Fourier Transform). This apparatus determines the phase coefficients as constantly “1” when performing the FHT, and changes the input order of input data to a reverse order of bits when performing the FFT. In addition, the apparatus, which can process a plurality of input data sets simultaneously, classifies the received signals into multi-path signals and multi-antenna signals, thus processing the multi-path signals separately from the multi-antenna signals, or directly processes multi-antenna signals.
