The multiple-input-multiple-output (MIMO) technique is widely used in modern wireless communication systems because it greatly increases system capacity and improves communication reliability. However, MIMO detection is a challenging task. Sphere detection algorithms are preferred in practice as these can achieve bit error rate performances close to that of the maximum likelihood algorithm. Sphere...
In wireless communication, Viterbi decoding algorithm (VDA) is the one of most popular channel decoding algorithms, which is widely used in WLAN, WiMAX, or 3G communications. However, the throughput of Viterbi decoder is constrained by the convolutional characteristic. Recently, the three‐point VDA (TVDA) was proposed to solve this problem. In TVDA, the whole procedure can be divided into three phases,...
A reconfigurable Viterbi decoder with high throughput and low complexity is presented in this paper. The proposed Viterbi decoder supports constraint lengths ranging from 3–9, code rates in the range of 1/2–1/3, and arbitrary truncation lengths. The decoder achieves a low bit error ratio in multiple standards, such as GPRS, WiMax, LTE, CDMA, and 3G. The proposed decoder is implemented on Xilinx XC5VLX330...
