Digital Up Conversion (DUC) encompasses an interpolating filter chain that transforms baseband signals into higher frequency signals suitable for transmission. This involves stages like half-band and CIC compensation interpolations to achieve high fidelity in spectral responses and minimize bandwidth loss.
The DUC effectively handles conversion tasks with precision, enabling swift transition of data rates necessary for top-tier LTE environments. Incorporating a numerically controlled oscillator and mixer, it balances interpolation factors and output sampling rates to meet rigorous standards in signal processing.
Faststream’s DUC solution is engineered for adaptability in FPGA structures, leveraging the stability of dedicated DSP units. This finely-tuned architecture allows for seamless integration into broader system designs, facilitating efficient resource utilization alongside consistent high-performance conversion operations.
