WebMar 16, 2016 · Well, the reason you do OFDM in the first place is that you can take a large piece of bandwidth, and instead of using it as a single channel that would be heavily frequency-selective, use it as a set of much narrower subchannels which can typically be considered to be represented by single tap channels. WebThe architecture-consists of a number of processing nodes connected through a high-bandwidth low-latency interconnection network. The physical memory in the machine is distributed among the nodes of the multiprocessor, with all memory accessible to each node. Each processing node, or cluster, consists of a small number of high-performance ...

Coherence bandwidth is a statistical measurement of the range of frequencies over which the channel can be considered "flat", or in other words the approximate maximum bandwidth or frequency interval over which two frequencies of a signal are likely to experience comparable or correlated amplitude fading. If … See more Frequencies within a coherence bandwidth of one another tend to all fade in a similar or correlated fashion. One reason for designing the CDMA IS-95 waveform with a bandwidth of approximately 1.25 MHz is because in many … See more • Coherence time • Coherence length See more If the delay spread D over a particular cellular communication path in an urban environment is 1.9 µs, then using equation above, the coherence bandwidth is approximately 0.53 MHz, which results in frequency selective fading over the IS-95 bandwidth.
