I. Turbo coding and decoding principleThe Turbo encoder is a parallel cascade convolutional encoding (Pccc,parallel concatenated convolutionalcode), which uses two 8-state sub-encoders and a turbo-in-code interleaving device. The code rate for the Turbo encoder is 1/3.Two. Emulation Link:Channel environment: Gaussian White NoiseSimulation parameters: R =1/3, constraint length =9,map interleaving: LTE interleaving deviceSimulation results:

make many of the masses of consumers can not touch the mind. After all, with Qualcomm, MediaTek and other familiar processor manufacturers compared to the core, whether in popularity, technology accumulation, shipments, etc. are far inferior. In the past, the United Core technology is not known because it has been focused on TD-SCDMA and TD-LTE technology research and development. But in fact, the United Core technology has also had its own glory. Th

When China's 3G construction is in full swing, some people begin to think about the next step of 3G to discuss the direction of 4G or even 5g. This is also a good topic, but it is obviously too early to be put on the agenda. The 4G standard is still under discussion, and the topic of 5g is even more false. Not long ago, at the IEEE Communications Association's Boston branch, analysts analyzed and studied 3G and 4G, and also believed that 5G may be unnecessary or even impossible. Some representa

At the same time, Nokia Siemens communication is ready for the evolution of TD-SCDMA to LTE technology, and will combine the best local R D partners and teams through global integrated product solutions, fully support the evolution of TD-SCDMA to

According to foreign media reports, the company plans to shut down its 2G network in 2017 due to the impact of ATT Mobility's redistribution of 2G network spectrum and deployment of more advanced services. The US telecom operator is now re-deploying its 1900 MHz PCS spectrum in New York City to switch Global Mobile Communication System services to HSPA + and LTE services. The company disclosed in a file submitted to the Securities and Exchange Commis

5G wireless technology overview, 5G Wireless Technology For 5G networks in 2018, two of the five most important wireless technologies-multi-input multi-output (MIMO) and beamforming-have always been important for 5G networks. MIMO and beam For LTE/4G, the industry is approaching the theoretical limit of time and frequency utilization. The next step of 5G wireless technology is to use the spatial dimension to send strictly focused signals to different
