Systems, methods, and devices to perform interleaving

摘要

An apparatus includes an interleaver configured to interleave encoded data and to output a series of interleaved bits to be transmitted via a 1 MHz orthogonal frequency-division multiplexing (OFDM) transmission. The apparatus also includes a modulator configured to modulate the interleaved bits and a transform module configured to transform the modulated bits. A transmit module of the apparatus is configured to transmit the transformed bits included in one or more spatial streams of the 1 MHz OFDM transmission.

1. A wireless communications apparatus comprising:
an interleaver configured to interleave encoded data and to output a series of interleaved bits, the interleaver comprising one or more stream interleavers corresponding to one or more spatial streams, the one or more stream interleavers configured to perform interleaving based on:
a block size of twenty four;an interleaver depth of eight;interleaved rotation indexes of 0, 2, 1, 3 corresponding to up to four spatial streams; anda base subcarrier rotation of less than or equal to nine; and a transmit module configured to transmit the interleaved bits included in the one or more spatial streams.
