hardofdm
- ofdm加窗前后的对比频谱图,以及循环前后缀重叠与不重叠两种情况的对比,最后给出了误码率的计算。-ofdm added after the contrast spectrum window, and the cycle before the suffix overlap and contrast the two cases do not overlap Finally, the bit error rate calculation.
wlan_transmitter
- WLAN仿真-发送机 wlan No Comments 设置完系统参数后,开始产生发送数据。 1. 产生随机的发送bit(tx_bits),这里不考虑信道编码。 2. QAM映射 3. 将数据映射到不同载波,形成OFDM符号 4. 产生pilot,并将pilot插入OFDM符号中 5. 加入dc和guard子载波 6. 进行ifft,将频域信号变到时域,并加入循环前缀 7. 对信号进行overlap window 8. 在时域产生short preamb
