TCM for OFDM-IM

TCM-coded OFDM assisted by ANN in Wireless Channels

The objective of this paper is to use Artificial Neural Network (ANN) in conjunction with M-ary PSK Trellis Coded Modulation (TCM) based Orthogonal Frequency Division Multiplexing (OFDM) as a means of achieving higher throughput and performance improvement in multipath fading channel. Simulation results are presented, that shows the superiority of the ANN-based approach, as a means to decode th...

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

Space-Time Block Coded and IQ-interleaved TCM, TTCM, BICM and BICM-ID Assisted OFDM

Space-Time Block Coded (STBC) In-phase Quadrature-phase (IQ)-interleaved Coded Modulation (CM) schemes are proposed for Orthogonal Frequency Division Multiplexing (OFDM). Trellis Coded Modulation (TCM), Turbo TCM (TTCM), Bit-Interleaved Coded Modulation (BICM) and Iteratively Decoded BICM (BICM-ID) schemes having a similar decoding complexity are employed in conjunction with 16-level Quadrature...

Traditional Chinese Medicine (TCM)

The Chinese medical view is that each living creature is a small part of the infinite universe, and is subject to the same laws that govern the rest of the cosmos. Therefore, an understanding of health requires an understanding of the laws of nature. The practitioner views health as a state of harmony existing between the internal environment of the body and the external environment it lives in...
