    摘要: A transmitter using a method of block code-based group modulation includes a grouping unit, a generating unit, and a mapping unit. The grouping unit generates symbols by grouping a data bit stream into N-bit groups, and the generating unit generates a codeword set composed of codewords corresponding to combinations of arrangements of pulses that are generated by a result of grouping to a predetermined number. Next, the mapping unit block-maps a codeword selected from the codeword set to groups constituting the symbols.

    摘要: A block-coded group modulation method includes generating a symbol by grouping at least one bit of a data bit stream into one group, classifying the symbol into an n number of sections, and generating an n number of initial information bits. Next, the method includes setting up the size of a pulse corresponding to signal energy transmitted through each of the n sections, generating an additional information bit on the basis of the number of cases according to the sequence of the energy sizes, and generating final information bits by inserting the additional information bit into the initial information bits.

    摘要: A base station and a terminal for supporting a low power mode are provided. The base station transmits a first type of beacon signal for a terminal operating in a normal mode, a second type of beacon signal for a terminal operating in a low power mode, and a charging signal for a terminal in a low power mode. The terminal harvests energy from a charging signal and receives the second type of beacon signal using the harvested energy. The terminal confirms a communication request through the second type of beacon signal, enters into an active period, and communicates with the base station.

    摘要: In a local wireless communication system, a reception signal including an STF (short training field) in which a plurality of patterns are repeatedly transmitted is received, the STF including a first number of STF patterns and a second number of STF patterns, the second number of STF patterns having an opposite code to that of the first number of STF patterns. In a first frequency offset estimation and correction process and a second frequency offset estimation and correction process, frequency offset estimation is performed on a plurality of STF patterns to acquire a phase error of each sample constituting the STF patterns, and the frequency of the STF patterns is corrected based on the acquired phase error. Cross correlation is performed on a predetermined number of STF patterns, among a plurality of STF patterns output subsequent to the frequency offset estimation and correction, to detect frame timing.
