A low phase noise voltage-controlled oscillator for mm-wave applications is presented. The oscillator uses switched-capacitor technique to increase the tuning range. The measured results show that the oscillator achieves a phase noise of −100dBc/Hz at 1MHz offset from the carrier frequency of 49.7GHz, while consuming 5.5mA current from a 0.9V supply. A wide tuning range percentage of 12%, i.e. 43...
For multicell MIMO interfering broadcast channels (IFBC), the zero-forcing-based approach can achieve the near optimal performance at high signal-noise-ratio (SNR) regime. However, the drawback of the zero-forcing-based approach is the poor performance in low SNR regime compared to the conditional match filter receive scheme. In order to address this problem, we propose an algorithm for minimizing...
