Optimal Number of Pilots for OFDM Systems
نویسندگان
چکیده
The study addresses channel estimation by inserting pilots in the frequency domain, showing the performance of OFDM systems as a function of the number of pilots inserted. The channel estimation and performance analysis were done using the parameters BER (Bit Error Rate) and throughput, and characterized by the number of pilots inserted. Simulations show the influence on the BER by the number of inserted pilots and throughput performance. One of the most important applications for this study is in underwater acoustic communications, which works naturally with bands of lower frequencies. Thus, it is essential to use an adequate number of pilots in order to minimize the loss in the troughput of the system.

This paper explores channel estimation using superimposed pilots for OFDM systems. The pilots are added linearly to the modulated symbol at a fraction of the total transmit power, making the method spectrally efficient. We present a series of receivers in which complexity is traded for performance; in particular, a receiver that achieves the theoretically lowest BER but has high complexity and ...
