Examples of cloaking patterns for damping distribution are: Seeing the full definition of occultation in the English Language Learners Dictionary Fading can lead to poor performance in a communication system, as this can result in a loss of signal power without reducing noise power. This signal loss may extend over part or the total bandwidth of the signal. Erasure can also be a problem, as it changes over time: communication systems are often designed to adapt to such deficiencies, but erasure can change faster as adjustments can be made. In such cases, the probability that a bland (and bit defects associated with the drop in signal/noise ratio) on the channel occurs on the channel becomes the limiting factor in left performance. When you hide the blocks, the fading process is almost constant for a series of symbol intervals.  A channel can be “double blockfading” if it blocks both in the temporal domain and in the frequency domain.  The terms slow and fast erasure refer to the speed at which the size and phase change that the channel imposes on the signal. Consistency time is a measure of the minimum time required for the change in size or phase change of the channel not to be correlated to the previous value. Because the frequency of a signal varies, the magnitude of the change varies. Consistency bandwidth measures frequency separation, after which two signals are detected by non-correlative discoloration. Diversity can be achieved in time, frequency or space. Common techniques for overcoming signal interference are as follows: In a fast-fading channel, the transmitter can use variations in channel conditions using the diversity of time to increase the robustness of communication to a temporary deep mask.
Although deep bland may temporarily remove some of the transmitted information, the use of a code correcting errors with bits successfully transmitted during other time intervals (interleaving) can allow the recovery of inflated bits. In a channel that is slowly fading, it is not possible to use time diversity, as the transmitter sees only one realization of the channel in its limitation of delay. A deep bland therefore maintains the entire duration of the transmission and cannot be mitigated with coding. Trails are a particular case of discoloration used to describe constructive interference in situations where a radio signal is gaining strength.  Some multipathic conditions thus increase the amplitude of a signal, as signals that travel in different ways arrive in phases to the receiver and become additively the main signal. Therefore, the total signal that reaches the receiver will be stronger than the signal would have been without the multipathic conditions. The effect is also noticeable on Wi-Fi systems.  The effects of discoloration can be combated by using diversity to transmit the signal through several channels that will be independently discolored and combine them consistently on the receiver. The probability of having a cover in this composite channel is then proportional to the probability that all component channels will experience bland at the same time, a much more unlikely event. Selective occultation or selective stretching of frequencies is an anomaly of radio propagation that is caused by the partial interruption of a radio signal itself – the signal reaches the receiver by two different paths, and at least one of the paths changes (extension or shortening).
