Introduction for Digital-RF System Design in Cellular

Abstract: 

In IC design, high performance, low power consumption, and low chip die size are very important to take into be considered with trade-off. Moreover, 5G or beyond 5G provides the high throughput and high-quality internet access (e.g., high-order QAM support up to 1K or 4K-QAM) even under harsh wireless environmental conditions. The high-order QAM needs high transmitted (Tx) EVM or received (Rx) SNR requirements. However, the Tx EVM or Rx SNR would be dominated by RF circuits impairment due to imperfect factors (e.g., RF noise, amplifier non-linearity, and I/Q imbalance, etc.) and in-chip interference. Advanced technologies have continually been investigated or designed to compensate these RF impairments and cancel noise (or in-chip interference) to enhance system performance. In this presentation, we will also show some digital assisted methods and measurement results.
