(English Abstract) |
The limitation of error vector magnitude (EVM) performance of transmitters based on I/Q mismatching due to high frequency signals has been investigated. The proposed radio frequency modulation is capable of generating a single sideband frequency without implementing a quadrature local oscillator which displaces a phase of a local oscillating signal by 90 degree at a high frequency. This technique is promising for the radio transmission of high SSRR more than 60 dBc. Also, the architecture of digital-IF transmitter using the proposed SSM can be applied for a future software-defined radio (SDR) solution supporting multiband and multimode wireless communications.
