A TRANSMITTER, CELLULAR COMMUNICATION SYSTEM AND METHOD OF TRANSMITTING THEREFOR |
摘要 |
<p>A transmitter comprises functionality (101) for receiving a sequence of input modulation symbols. An M-point discrete Fourier transform (105) is applied to the block of input modulation symbols resulting in a frequency domain symbol block. This block is fed to an N-point inverse discrete Fourier transform (105) (N>M) thereby generating a time domain transmit signal. In addition, the transmitter (200) comprises a phase rotation processor (201) which phase rotates the input modulation symbols in multi-symbol intervals. The phase rotations applied within each interval are constrained in accordance with a first phase rotation constraint requirement whereas the phase rotations between consecutive symbols belonging to different intervals are constrained in accordance with a different phase rotation constraint requirement. The invention may allow interference mitigation by reducing alignment between quadrature channels of the transmitter and interferers.</p> |
