This paper presents an ultra-high-speed/area-efficient Polar encoder design with very high system throughput for emerging next-generation 5G applications. In a demonstrated design example, the proposed hardware architecture is mainly based on 16-parallel radix-2 processing engines. An 8192-point Polar encoder is designed and synthesized with TSMC 40-nm CMOS technology, operating at clock frequency...
Polar Codes become a new channel coding, which will be common to apply for next-generation wireless MIMO communication systems. In this work, we propose LEGO-based VLSI hardware design and implementation of the Polar encoder using radix-2 processing engines, which features low area cost, low power dissipation, high speed, and high throughput via serial computation. Under TSMC 90nm CMOS technology,...
Polar Codes applied for next-generation MIMO systems is an emerging research topic. In this work, we propose an efficient VLSI hardware architecture of the Polar encoder using radix-k processing engines. Under TSMC 90nm CMOS technology, the 16384-point radix-2 based Polar encoder design is synthesized with 0.244mm2 under maximum clock frequency of 2.0GHz. In the similar manner, the VLSI hardware can...
The forecasting accuracy of port throughput is influenced by many complicate socio-economic factors, especially by nonlinear and fluctuation signal included in the history sequence of port throughput. To deal with the nonlinear and fluctuation signal in the history sequence, this paper introduces the parameter projection pursuit regression (PPPR) method to the port throughput prediction field. In...
In wireless access networks the traffic load varies strongly along a day and efficient concepts to adapt the power consumption of LTE macro base stations to the required traffic load are currently widely under study. Significant daily energy savings up to 35% can be achieved for different deployment scenarios by introducing energy adaptive hardware features in combination with energy aware scheduling...
Hotspot wireless service attracts more and more attention all over the world. The demands for convenient, low-power, cost-effective, reliable hotspot access service urges the new technology emerging. The existing wireless access service system could not fulfill all of the above requirements for quickly growing users. Wireless AP (access point) and router system provide only networks access service,...
As the world moves into wireless communication times, there is an increasing demand for reliable, low-power, cost-effective, easy-to-access storage that can still provide adequate performance for multi-userspsila information retrieval. However, there is no current wireless system adequately fulfills all of these requirements of storage service. Wireless AP (access point) and router system provide...
This paper shows a triple-mode LDPC decoder design with two design techniques, the matrix reordering algorithm for multi-mode reconfiguration and the single-entry-multiple-data (SEMD) scheme for throughput enhancement. The matrix reordering algorithm can reduce the computational complexity from O(n!) to O(n3). The SEMD can enhance the throughput by m times with small area overhead. With TSMC 0.13...
This paper presents the LDPC decoder chip for (1944,972) QC-LDPC codes in IEEE 802.11n communication system. The efficient LDPC decoder chip is designed with three design techniques, including Group Comparison (GC), Dynamic Wordlength Assignment (DWA), and Data Packet Scheme (DPS). When the target BER is 10-6, the decoding performance can be improved by the coding gain of 0.48 dB and 0.63 dB with...
