Signal transmission method and system of hand mobile digital multimedia transmission system



This invention provides a signal transmission method and a system suitable for mobile handheld multimedia application, which receives input of multiple data streams, arranging the received data streams to a data set in equal intervals, converting the data set of FFT to generate a time domain known sequence, forming the known sequence and system information to a frame head and the known sequence and the data set by FFT conversion to a frame to be matched in rate to form a complete frame structure to be output, which utilizes time domain known information to carry out channel estimation and synchronization without frequency domain pilot signals and there are many selections to time domain sequence and the data frame composing a super frame head is added with frequency expansion protection system information.
