Abstract: An Orthogonal Frequency Division Multiplexer (OFDM) transmitter and receiver apparatus consistent with certain embodiments of the present invention receives data to be transmitted and maps (204) a first portion of the data to a first polarization state and a second portion of the data to a second polarization state. A first transmitter (216) transmits the first portion of the data as a set of first OFDM subcarriers using an antenna (230) exhibiting a first polarization. A second transmitter (234) transmits the second portion of the data as a set of second OFDM subcarriers using an antenna (240) exhibiting a second polarization, wherein the first polarization is orthogonal to the second polarization. A receiver apparatus uses a first antenna (302) exhibiting the first polarization and a second antenna (306) exhibiting the second polarization. A first OFDM receiver (310) receives a first set of polarized OFDM subcarriers from the first antenna (302) while a second OFDM receiver (324) receives a second set of polarized OFDM subcarriers from the second antenna (306). A decoder (330) decodes the first and second sets of OFDM subcarriers and combines them into a stream of data.

Abstract: An Orthogonal Frequency Division Multiplexer (OFDM) transmitter and receiver apparatus consistent with certain embodiments of the present invention receives data to be transmitted and maps (104) a first portion of the data to a first polarization state and a second portion of the data to a second polarization state. A first transmitter (148) transmits the first portion of the data as a set of first OFDM subcarriers using an antenna (160) exhibiting a first polarization. A second transmitter (156) transmits the second portion of the data as a set of second OFDM subcarriers using an antenna (164) exhibiting a second polarization, wherein the first polarization is orthogonal to the second polarization. A receiver apparatus uses a first antenna exhibiting the first polarization and a second antenna exhibiting the second polarization to receive and decode first and second set of OFDM subcarriers and combines them into a stream of data.
Abstract translation: 与本发明的某些实施例一致的正交频分复用器（OFDM）发射机和接收机设备接收要发送的数据，并将数据的第一部分（104）映射（104）到第一极化状态和第二部分数据到 第二极化状态。 第一发射机（148）使用表现出第一极化的天线（160），将数据的第一部分作为第一OFDM子载波的集合发射。 第二发射机（156）使用表现出第二极化的天线（164）将数据的第二部分作为第二OFDM子载波的集合发送，其中第一极化与第二极化正交。 接收机装置使用呈现第一极化的第一天线和展现第二极化的第二天线来接收和解码第一和第二组OFDM子载波，并将它们组合成数据流。
