摘要： Provided is a communication method for improving the communication quality of multicast transmission. A grouping table storage section stores a grouping table in which Ack return order positions indicating priority orders of the reception terminals which each return an Ack, and addresses of the reception terminals are set. An Ack return order position notification frame creation section notifies each reception terminal of a corresponding Ack return order position based on the grouping table. An Ack return permission information determination section refers to the grouping table, determines the number of reception terminal that are to be permitted to return an Ack, and creates Ack return permission information in which information about the reception terminals that are to be permitted to return an Ack is set, based on the determined number of reception terminals. A multicast creation section creates a multicast containing the Ack return permission information and transmission data.

摘要： The present invention aims to provide a transmission device that, in a communication system using multilevel modulation with 2^n levels (n being an integer greater than or equal to two), limits the run length to a predetermined value or less and guarantees DC balance.The transmission device, which transmits data to which 2^n amplitude modulation has been applied, separates data for transmission into n data sequences; encodes one of the n data sequences to guarantee run length, thereby generating a converted data sequence; generates an intermediate data sequence by either inverting or not inverting a specific data sequence so that, based on candidate data, the next output voltage guarantees DC balance; and applies 2^n amplitude modulation to n-bit symbols each of which has a bit in the intermediate data sequence as a most significant bit and bits in the remaining data sequences, excluding the specific data sequence, as subsequent bits.

摘要： A master device transmits a beacon signal including information related to a proximity wireless communication area in a predetermined cycle by using a transmission power which allows the beacon signal to reach beyond the proximity wireless communication area. When a slave device receives the beacon signal from the master device, the slave device estimates a distance to the master device in accordance with the information of the beacon signal. When a wireless communication terminal is located within the proximity wireless communication area, the slave device is connected to the master device by using a proximity wireless communication.

摘要： A reception station 1b compares its BSSID with BSSID included in a signal that has arrived thereat. As BSSIDs included in signals transmitted by interfering stations 1c and 1d both match BSSID of the reception station 1b, the reception station 1b identifies each of the interfering stations 1c and 1d as a non-suppression target transmission source. As neither of BSSIDs included in signals transmitted by interfering stations 2a and 2b matches BSSID of the reception station 1b, the reception station 1b identifies each of the interfering stations 2a and 2b as a suppression target transmission source. The reception station 1b uses characteristic amounts of signals that are associated with the interfering stations (i.e., suppression target transmission sources) 2a and 2b and that have been measured in the past as characteristic amounts of interfering signals that are used to suppress the interfering signals from a received signal.

摘要： A signal transmitted to an STA 200a from a communication device AP is also received by an STA 200b. Upon reception, the STA 200b measures an RSSI. The STA 200b then creates a state notice frame which includes the measured RSSI, and transmits it to the AP 100. In accordance with the received state notice frame, the AP 100 determines and updates a PHY rate for transmission to the STA 200b. This allows to increase the determination and update frequency of PHY rates than before, resulting in an improved possibility of coping with rapid changes in channel environments.

摘要： A spreading code generating apparatus carries out M-sequence multiplication and zero value addition of generated orthogonal codes to obtain channel identification codes, and then carries out inverse Fourier transform of the channel identification codes to generate spreading codes and inverse spreading codes. A transmitting apparatus and a receiving apparatus store the spreading codes and the inverse spreading codes generated by the spreading code generating apparatus, respectively, and use a single code respectively selected from the stored codes to carry out spread spectrum communication. With the use of the spreading codes for spreading, the input signal is spread over a wide frequency band with uniform power on the frequency axis. Thus, transmission characteristics are improved, and multiplexing capacity is increased.
