POWER DISTRIBUTION AND SYNCHRONIZATION SCHEME WITH SUPERIMPOSED TRAINING SEQUENCES

It is a good choice for OFDM systems using superimposed training sequences to achieve synchronization, channel estimation and equalization, etc. However, many problems such as superimposed training power distribution are still open for us to solve. The power distribution scheme and the synchronization scheme with superimposed training are proposed to solve these problems. Theory analysis and simulation show that these schemes are useful for OFDM systems with superimposed training to improve the performances.
