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.

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： In this signal detection device (100), a delaying unit (101) delays a first distributed signal or a second distributed signal distributed from a received signal for a period of time of T1 to form a first multiplication signal, and delays the one for a period of time of T2 (T2>T1) to form a second multiplication signal. An integrator (104) calculates a first correlation value by integrating the result of multiplying the first distributed signal and the first multiplication signal. An integrator (105) calculates a second correlation value by integrating the result of multiplying the second distributed signal and the second multiplication signal. An evaluation unit (108) evaluates whether the signal to be detected, which is a periodic signal with a period of T1 or a periodic signal with a period of T2, exists or not, on the basis of the first correlation value and the second correlation value.

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.
摘要翻译： 接收站1b将其BSSID与包括在已经到达的信号中的BSSID进行比较。 由于由干扰站1c和1d发送的信号中包括的BSSID都匹配接收站1b的BSSID，所以接收站1b将每个干扰站1c和1d识别为非抑制目标传输源。 由于由干扰站2a和2b发送的信号中包括的BSSID都不与匹配接收站1b的BSSID，所以接收站1b将每个干扰站2a和2b识别为抑制目标传输源。 接收站1b使用与干扰站（即，抑制目标发送源）2a和2b相关联的信号的特征量（即，抑制目标发送源）2a和2b，并且作为用于抑制干扰信号的干扰信号的特征量， 接收信号。
