To improve the signal to noise ratio in the auto-tracking receiver, the traditional two dimensional acquisition algorithm is often used. However, its application has been limited because of the large amount of calculations. In this paper, a low-complexity cross-correlation algorithm is proposed. Firstly, the theoretical deviation is given. And then its implementation based on Field Programmable Gate...
Conventional orthogonal frequency division multiplexing (OFDM) communication systems are typically designed assuming additive white Gaussian noise and interference statistics. However, in many applications, such as Wi-Fi and powerline communications (PLC), impulsive statistics are often observed. Impulsive noise can degrade the signal-to-noise ratio (SNR) of all subcarriers and impair communication...
This paper presents a hardware scheme based on FPGA to implement the 3780 points FFT. The simulation result shows that this design can satisfy the requirement of the DTTB transmitter and can acquire the better performance than typical schemes.
