摘要： A transmitter includes an encoding module, an adaptive hierarchical signal mapping module and a transceiver module. The encoding module receives an input signal and encodes the input signal. The input signal includes data to be transmitted. The adaptive hierarchical signal mapping module modulates the encoded signal according to one or more hierarchical level distance ratios to obtain modulated symbols. The hierarchical level distance ratio defines distances between the modulated symbols. The transceiver module generates a radio frequency signal according to the modulated symbols and transmits the radio frequency signal to an air interface.

摘要： A method used for digital right management (DRM) of system-on-chip (SOC) IP by making use of a system platform, which provides an encryption & protection mechanism created by incorporating the IP designer, the IP supplier, the wafer manufacturer, the customer, and the electronic design automation (EDA) tool, thus establishing an integral and efficient SOC IP management and protection platform. In this method, the IP core hardware program codes are protected through incorporating an IP identification code (comprising a general ID code and a security ID code) into the behavior design level of the IP core hardware program codes and utilizing a public key encryption protection of the SOC IP. Therefore, through such a kind of encryption, the customer is not able to perceive the existence of the IP identification code. In addition, a SOC IP fingerprint is included in the security ID code of the IP identification code, thus the customer engaged in the illegal distribution of copies of IP can be traced through the SOC IP fingerprint.

The data switching system further includes a plurality of pre-processors to manage the input timing of data packets into the switching matrix array in order to avoid output conflict.
