Abstract |
|
|
| : Energy Spreading Transform (EST) system can extend the energy of the signal to both the time domain and frequency domain. In the system which is not encoded, EST has been widely concerned because that it enables the system performance approach the matched filter limit. The existing literature mainly discussed EST iterative detection performance under the conditions of the ideal channel estimation, while it did not consider the possible impact of channel estimation error. Under the doubly selective channel conditions, this study took a theoretical analysis of the system demodulation algorithm in the presence of channel estimation error, and also verified the impact of channel estimation error in different channel environments using simulation.. |
