Performance analysis and optimal power allocation for linear receivers based on superimposed training
Performance analysis and optimal power allocation for linear receivers based on superimposed training
In this paper, we derive a performance comparison between two training-based schemes for multiple-input multiple-output systems. The two schemes are the time-division multiplexing scheme and the recently proposed data-dependent superimposed pilot scheme. For both schemes, a closed-form expression for the bit error rate (BER) is provided. We also determine, for …
