Abstract
An improved interleaver design to fully explore the diversity of the MIMO OFDM systems provides higher diversity gain than usual. A method for wireless data communication using such interleaver design implements parsing a bit stream into multiple spatial data streams, interleaving the bits in each spatial data stream by performing bit circulation to increase diversity of the wireless system, and transmitting the bits of each spatial data stream.
Claims12
A method of data communication in a wireless system, comprising the steps of:
- parsing a bit stream into multiple spatial data streams;
- interleaving the bits in a spatial data stream by steps including bit circulation to increase diversity of the wireless system;
- forming new data streams by bit combining after the bit circulation;
- and
- transmitting the bits of each newly formed spatial data stream.
2 more elements
A wireless communication system, comprising:
- a transmitter including:
- a parser that parses a bit stream into multiple spatial data streams;
- multiple interleavers corresponding to the multiple spatial data streams, wherein each of one or more interleavers performs interleaving of the bits in each of one or more spatial data streams by steps including bit circulation to increase diversity of the wireless system, the interleavers further forming new spatial data stream by bit combining after the bit circulation;
- a modulator that transmits the bits of each newly formed spatial data stream;
- and
- a receiver that receives and deinterleaves the transmitted bits.
