The processing complexity of optimal receivers in frequency selective channels grows exponentially with the channel memory length. Linear receivers, alternatively, offer significantly less complexity with the cost of performance degradation. Such degradation can be due to not fully capturing the inherent frequency diversity or degraded coding gain. In this paper we investigate how effectively t...

Symbol-by-symbol maximum a posteriori (MAP) decoding algorithms for linear nonbinary block and convolutional codes over both extension elds GF(q = p a) and integer rings Z q are presented. Equivalent MAP decoding rules employing the dual code are given which are computationally more eecient for high-rate codes. The suitabil-ity of the proposed algorithms is demonstrated by applying them to a pa...

place is a part of geographical space and a base for establishment of social relations. each place is unique according to its specific properties, functions and history. meanwhile, some places find symbol identity due to their especial historical events and properties and this identity would be maintained in the minds and moved to the other generations. for example azadi tower in tehran and sav...

syntax rules Abstract syntax rules from the language definition are directly translated to the ASM notation, using certain conventions that will be explained by examples. Basically, an abstract syntax rule can be understood as declaring one or more (tuple) domains, and defining functions to construct and select values of the component domains. However, syntax nodes have an identity as opposed t...

abstract this study aims to examine the use of religion heritage and application of the prophet job’s character mask. one of the important masks that have been used by contemporary poets is the prophet’s masks, especially the job of which the story exists in the quran. this character is a symbol of patience. darvish and sayyab are the most important poets who used the mask of this character.  e...
