Abstract
- This paper proposes a shortened transmit technique using repetitive transmission in the frequency domain. For a single antenna OFDM system, a hybrid selection combining and maximum ratio receive combining technique was proposed for better performance, but it is effective only for high Eb/N0 region. This paper suggests a new method of removing zeros generated from repetitive transmission and of reconfiguring repetitive transmit time domain signals for maximum ratio receive combining at the receiver, by which we can obtain better performance comparing to SISO case at the expense of a few algebraic calculations and FFT/IFFT executions.
