摘要： A method for coexistence of an orthogonal frequency division multiple access (OFDMA) receiver (117) such as a WiMAX receiver with a synchronous frame-based transmitter (115) such as a Bluetooth transmitter within a mobile station (110) receives an estimated media access protocol (MAP') signal indicating when a MAP message is expected to be received by the OFDMA receiver (117) and uses it at a Bluetooth shutdown signal (190) at least when a MAP message is expected to be received. The MAP' signal can be taken directly from the ODFMA transceiver (117) or it may be produced through analysis of a receiver-enable (RXE) signal that includes not only MAP symbols but also downlink data symbols. The RXE signal can be analyzed using interrupt-and-timer, Fast Fourier Transform, covariance, and/or delay-locked loop techniques to extract historical MAP symbol information and generate expected MAP symbol information. Shutting down a Bluetooth transmitter during expected MAP message receipt permits the OFDMA receiver to maintain synchronicity with an access point while not requiring the Bluetooth transmitter to shut down every time the OFDMA receiver expects to receive an OFDMA symbol.

摘要翻译：一种用于共享诸如WiMAX接收机的正交频分多址（OFDMA）接收机（117）与诸如移动台（110）内的蓝牙发射机之类的基于同步帧的发射机（115）的方法，接收估计的媒体接入协议（MAP'）信号，指示何时期望OFDMA接收机（117）接收MAP消息，并且至少在预期接收到MAP消息时，使用它在蓝牙关闭信号（190）。 MAP'信号可以直接从ODFMA收发器（117）获取，或者可以通过分析不仅包括MAP符号而且包括下行链路数据符号的接收机使能（RXE）信号来产生。可以使用中断和定时器，快速傅里叶变换，协方差和/或延迟锁定环技术来分析RXE信号，以提取历史MAP符号信息并生成预期的MAP符号信息。在期望的MAP消息接收期间关闭蓝牙发射器允许OFDMA接收机与接入点保持同步，而不需要蓝牙发射器在OFDMA接收机期望接收OFDMA符号时关闭。

摘要： A technique for providing broadcast services to a subscriber station includes determining (904) when a first broadcast frame that is to be transmitted on a broadcast channel includes broadcast information that is to be received by the subscriber station. Next, cellular information that is included within a first cellular frame and that is to be received by the subscriber station is scheduled (906), based on the determining, to avoid conflict between receipt of the cellular information and the broadcast information at the subscriber station. Finally, based on the scheduling, the first cellular frame is transmitted (908) on a cellular channel.

摘要： A correlation system for use in wireless direct sequence spread spectrum systems includes an RF down converter (12) which receives an encoded signal and generates therefrom analog in-phase (I) and quadrature (Q) signal components. These components are digitized and the digitized signals are then passed to each of the high precision correlator circuit (22) and a low precision correlator circuit (28). The low precision correlator circuit (28) consists of a bank of a plurality of low precision correlators which receive the I and Q signal components as inputs and correlates the same with progressively phase shifted or delay pseudo noise (PN) codes. A low precision correlator circuit (28) locks on to the appropriate PN code phase shift or delay and applies the same as a reference PN code to the high precision correlation circuit (22) for data acquisition and demodulation.
