Abstract :
We study OFDM symbol interleaver design for gigabit per second (Gbps) wireless communications over the millimeter-wave (mmWave) frequency band. A bit-reversal symbol interleaver is proposed, which significantly outperforms conventional block interleaver design. It is demonstrated that the new interleaver design can be naturally combined with FFT operation and simplifies the hardware implementation complexity, which is especially important for several Gbps throughput applications. Simple design parameters are also proposed which serve as new and effective metrics for interleaver designs.
