Business-use radio microphones, such as used in broadcast, a stage, and a concert, are called as specified radio microphones, and the frequency band of 770 to 806 MHz is used. It is necessary to migrate to other reallocated frequency (UHF and 1.2 GHz) band with rapid development of radio communications systems, such as a mobile phone. We are studying low delay digital transmission for specified radio microphone that enables low delay, high-quality and stable transmission of radio microphone signals in the new reallocated frequency band. We use OFDM modulation in consideration for information rate and robustness for multipath. We conducted computer simulation of transmission characteristics of proposed low delay digital transmission, and confirmed that 4-branch diversity reception greatly improved transmission characteristics. |
