Usage Efficiency

Quasi-cyclic low-density parity-check (QC–LDPC) codes are introduced as a physical channel coding solution for data channels in 5G new radio (5G NR). Depending on the use case scenario, this standard proposes the usage of a wide variety of codes, which imposes the need for high encoder flexibility. LDPC codes from 5G NR have a convenient structure and can be efficiently encoded using forward substitution and without computationally intensive multiplications with dense matrices. However, the state-of-the-art solutions for encoder hardware implementation can be inefficient since many hardware processing units stay idle during the encoding process. This paper proposes a novel partially parallel architecture that can provide high hardware usage efficiency (HUE) while achieving encoder flexibility and support for all 5G NR codes. The proposed architecture includes a flexible circular shifting network, which is capable of shifting a single large bit vector or multiple smaller bit vectors depending on the code. The encoder architecture was built around the shifter in a way that multiple parity check matrix elements can be processed in parallel for short codes, thus providing almost the same level of parallelism as for long codes. The processing schedule was optimized for minimal encoding time using the genetic algorithm. The optimized encoder provided high throughputs, low latency, and up-to-date the best HUE.

A hybrid simulation of the guidance and navigation system of the Apollo spacecraft is underway at the Massachusetts Institute of Technology Instrumentation Laboratory. The Apollo Guidance and Navigation equipment is digital, elec tronic, and electromechanical. The guidance and naviga tion analog and digital hardware is combined in simulation with analog and digital computers so that the hardware will be subjected to dynamic conditions approaching those found in a space environment. The instrumentation of the Apollo Guidance and Navi gation System is described as well as its adaptation to the hybrid simulation. Software models are discussed to indi cate some of the varied problems considered. Digital pro cedures which are designed to support the operator and enhance the reliability of the simulation are described. In conclusion, it becomes apparent that the judicious use of computers, together with guidance and navigation hardware and software, makes it possible to simulate in real time any part of the Apollo mission from lift-off to splash-down.
