    Abstract: PROBLEM TO BE SOLVED: To provide systems and methods that facilitate providing time-division duplexed beam-forming support in traditional non-time-division duplexed wireless systems, such as an OFDMA system, a WCDMA(R) system, etc.SOLUTION: A base station analyzes pilot information, such as a portion of bandwidth over which a user device is transmitting (402), and transmits on a downlink using a pre-hopped portion of bandwidth utilized by the user device on the preceding reverse link time slot (404).

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate transmitting low-density parity-check encoded communications in a wireless communication network and incrementing such codes in response to requests from receiving devices.SOLUTION: The LDPC codes have associated constraints allowing the codes to be error-corrected upon receipt. Requests for incremented codes are possible when the original code can be too error-ridden to properly decode, e.g. in the case of low transmission power or high interference. In this case, additional nodes can be added to current and/or subsequent communications to facilitate adding more complex constraints to the LDPC codes. In this regard, large codes require only a small number of validly transmitted nodes to predict error-ridden values as the additional constraints render less ambiguity in possible node value choices.

    Abstract translation: 要解决的问题:提供有助于在无线通信网络中传送低密度奇偶校验编码通信的系统和方法,并响应于来自接收设备的请求递增这些代码。 解决方案:LDPC码具有相关联的约束,允许在接收时对代码进行纠错。 当原始代码可能太错误以便正确解码时,可能需要递增代码。 在发射功率低或干扰较大的情况下。 在这种情况下,可以将附加节点添加到当前和/或后续通信,以便于向LDPC码添加更复杂的约束。 在这方面,大代码只需要少量有效传输的节点来预测误差值,因为附加约束在可能的节点值选择中呈现较少的模糊性。 版权所有(C)2012,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a transmitter generating a pilot having a constant time-domain envelope and a flat frequency spectrum based on a polyphase sequence.SOLUTION: A first sequence of pilot symbols is formed based on a polyphase sequence and replicated a plurality of times to obtain a second sequence of pilot symbols.

A cyclic prefix is appended to the third sequence of output symbols to obtain an IFDMA symbol, which is transmitted in the time domain via a communication channel. A pilot LFDMA symbol may also be generated with a polyphase sequence and multiplexed using TDM or CDM. A receiver derives a channel estimate based on received pilot symbols and using minimum mean-square error, least-squares, or some other channel estimation technique.
