Communication apparatus, wireless microphone system and communication method

A wireless microphone system comprising:

• a master device;
• and
• m (m:
• an integer of 2 or more) microphones which are connected to the master device for communication,
• wherein the master device includes
• a controller that generates a table in which a carrier wave and a slot to be used for communication with each of the m microphones are set for each one frame period, based on a default number of carrier waves based on a time division multiplex communication system and n (n:
• a default positive integer) slots constituting the one frame period of the time division multiplex communication system;
• and
• k (k:
• an integer of 2 or more) wireless processing units that perform communication using the time division multiplex communication system with corresponding individual microphones among the m microphones, based on the generated table,
• wherein the k wireless processing units respectively operate synchronously based on the same clock signal, and
• wherein the number C of communicable channels of the m microphones is C>k*{(n/2)−1} (*:
• multiplication operator).

A communication method using a communication apparatus connected to m (m:

• an integer of 2 or more) microphones for communication, the method comprising:
• generating a table in which a carrier wave and a slot to be used for communication with each of the m microphones are set for each one frame period, based on a default number of carrier waves based on a time division multiplex communication system and n (n:
• a default positive integer) slots constituting the one frame period of the time division multiplex communication system;
• and
• performing communication using the time division multiplex communication system with corresponding individual microphones among the m microphones, based on the generated table, by k (k:
• an integer of 2 or more) wireless processing units included in the communication apparatus,
• wherein the performing communication by the k wireless processing units has steps of respectively operating synchronously based on the same clock signal, and
• wherein the number C of communicable channels of the m microphones is C>k*{(n/2)−1} (*:
• multiplication operator).
