Latest Patents

One of Jiang Chang's latest patents is the "Scalable Multiuser Audio System and Method." This invention describes systems, methods, apparatuses, and computer program products for wireless in-ear monitoring (IEM) of audio. The system includes transmitters that map orthogonal sub-carriers of a digital signal to narrowband receivers, forming receiver-allocated audio channels. It modulates the digital signal and transmits it as an ultra-high frequency (UHF) analog carrier wave comprising the orthogonal sub-carriers to nearby receivers. The narrowband receiver is designed to demodulate and sample the sub-carriers allocated to it. The sub-carriers can be positioned orthogonal to one another in adjacent sub-bands of the frequency domain. Additionally, beacon symbols and pilot signals can be iteratively provided in the same portion of the frequency domain for each channel. The receiver employs both non-data-aided and data-aided approaches for synchronizing the time domain and frequency domain waveforms of the received signal to the transmitted signal before sampling the allocated sub-carriers.
