Faststream Technologies offers a comprehensive Digital Up Conversion (DUC) solution that is integral to modern communication systems. The DUC system includes an interpolating filter chain, numerically controlled oscillator (NCO), and mixer, which together facilitate the conversion of baseband signals to a higher frequency for transmission. The filter chain, a key component in this process, includes various interpolators and compensators that ensure efficient and accurate signal conversion across multiple stages.
Comprising low-pass, half-band, CIC compensation, and CIC interpolators, the DUC's filter chain is designed to maximize resource efficiency by employing multiplier sharing techniques. Such advanced methodology enables optimal use of FPGA resources, supporting a high interpolation factor necessary for upscaling the signal.
The DUC's design allows for flexible operation across a range of clock rates, making it highly adaptable to varying application requirements. This adaptability is essential for LTE and 5G systems that mandate robust data conversion capabilities at high performance levels. Faststream Technologies enhances the digital signal processing efficiency, aiding in achieving higher data rates and reduced power consumption.
