摘要： Television receivers receive a television signal and downconvert the television signal to generate a complex baseband signal. The complex baseband signal is differentiated and then integrated to reduce a direct current (DC) offset in the complex baseband signal. The television receiver may include a periodic known information field. The known information field is correlated with the integrated signal to determine a residual offset therein that is associated with a constant used in integrating the differentiated complex baseband signal. The residual offset is subtracted from this constant when integrating the differentiated complex baseband signal.

摘要： A communication station such as a hand-held telephone quickly identifies a desired carrier signal or time slot of a carrier signal and synchronizes itself in time and frequency to that carrier or slot. Synchronization is achieved even when frequency and time reference signals in the communication station are offset, e.g., due to drift, with respect to the carrier signal or slot by averaging successions of signal measurements that occur at times when corresponding signal values are expected. In one method, a plurality of measurements of the received signal taken at a group of predetermined time points where corresponding values are expected are averaged together, in order to enhance the signal to noise ratio. Averaging is carried out several times using different groups of time points, the groups corresponding to respective, different expected clock frequency errors. The results of the averaging steps are used in determining a best hypothesis for the received signal. Dynamic programming is used to test synchronization hypotheses based on different hypotheses of timing drift rate and to discriminate between different hypotheses of timing and timing drift rate in order to maximize sums of correlations.
摘要翻译：诸如手持电话的通信站快速识别载波信号的期望的载波信号或时隙，并将其自身在时间和频率上同步到该载波或时隙。即使在通信站中的频率和时间参考信号由于相对于载波信号或时隙的偏移而被偏移，即通过平均在预期相应的信号值时发生的信号测量的次序来实现同步。在一种方法中，在预期相应值的一组预定时间点取得的接收信号的多个测量值被一起平均，以增强信噪比。使用不同的时间点进行多次平均，这些组对应于相应的不同的预期时钟频率误差。平均步骤的结果用于确定接收信号的最佳假设。动态规划用于基于不同的定时漂移速率假设来测试同步假设，并且对不同的定时和定时漂移率的假设进行区分，以便最大化相关的和。

In a representative embodiment, the system comprises means (50-54) for providing a set of all possible N-bit values as a plurality of mutually exclusive subsets each containing at least one possible N-bit value; means (56-60) for comparing the N-bit input value with each of the subsets to determine to which one of the subsets the N-bit input value belongs; and means (64) for selecting as the transformed N-bit output value an N-bit value from another one of the subsets. In accordance with the present invention, each of these subsets may be cyclically generated in a linear feedback shift register (LFSR) or, alternatively, stored in a memory.

摘要： A method and system for increasing the signal margin of a radiocommunication link to provide a short message service which is reliable, even under non-ideal conditions. According to the method, short alphanumeric messages can be transmitted over the broadcast control channel of a digital radiocommunication link, or another communication channel consisting of one or more slots from successive frames in a TDMA communication link. An increase in transmission power is used in combination with repetition to increase effective signal margin without complications in the mobile unit design, significant delay, or co-channel interference. Where a more significant increase in signal margin is desired, when a longer message is required, or for voice messages, the message may be stored and the mobile unit alerted of the message.

摘要： A method and receiver which provides, among other features, for resubtraction of an already subtracted signal in order to eliminate subtraction errors, termed re-orthogonalization, is described herein. According to exemplary embodiments, pairwise combinations of spreading codes are used to despread received composite signals. For example, these pairwise combinations can include a first spreading code associated with a signal that has already been subtracted and a second spreading code associated with a signal which is weaker than that associated with the first spreading code. In this way both resubtraction and subtraction are performed at the same time.

摘要： A method and apparatus of communicating information using Time Division Multiple Access and adaptive transmission and reception are disclosed. Signal bursts are transmitted from TDMA transmitters to a TDMA receiver wherein the transmitter codes the information and transmits coded information to the receiver using at least one of two timeslots of a plurality of timeslots in a repetitive TDMA frame period. Both of the two timeslots are received whether or not the transmitter has transmitted using one or two timeslots and the received signals are classified as intended and non-intended. Successively received signals classified as intended are then assembled into a block for decoding to reproduce the information.
