ppt.rar - After identifying the best MNT− 1 nodes with the simplified branch metric and the accumulated branch metric at stage NT − 1, we then calculate the LLR of each coded bit utilizing the standard squared Euclidian distance metric.
The log-likelihood ratio (LLR) of a posteriori probability (APP) of each coded bit conditioned on the received signal y is normally calculated using the max-log approximation.

narayani__ref.rar - A multiplexing system with NT transmit and NR equals NT receive antennas is designed.
The main challenge fo systems lies in the non-orthogonality of the transmission channel.
This can be solved by turbo processing.
Turbo channel encoder is used for converting the bits in its suitable form.
Then different M-ary QAM is compared.

doc.rar - The primary objective of the QRD-M detector is to identify the candidate list.
The QRD-M algorithm is a breadth-first tree search.
It views all the branches it will ever consider for a given stage of the detection tree and then rejects all but the Mi best nodes at the i-th detection stage before continuing on to the next stage.

2modulesPppt.rar - A dynamic estimation of channel is necessary before the transmission of the signals since the wireless channel is time–varying..we use MMSE method for channel estimation. The MMSE method calculates the following, MMSE channel estimator is designed to minimize the estimation MSE. The MMSE estimate the channel responses.,2013-11-13 18:24:50,下载10次
code.rar - EEOTS algorithm In this paper We merge two unconnected concepts
(i) Channel coding can be used to conserve energy by transmitting at reduced power levels over longer durations.
(ii) Electro-chemical mechanisms in batteries allow them to recover energy during idle periods.
Two kinds of delay constraints were considered, one a deadline constraint and the other an average delay constraint.
We achieve an Energy Efficient transmission compared to an other algorithms.

main.rar - We formulate a scheduling problem that takes into account different hardware delays experienced by the secondary users
(SUs) in a centralized cognitive radio network (CRN) while switching to different frequency bands. We propose a polynomial-time
suboptimal algorithm to address our formulated scheduling problem. We evaluate the impact of varying switching delay, number of
frequencies, and number of SUs. Our simulation results indicate that our proposed algorithm is robust to changes in the hardware
spectrum switching delay and its performance is very close to its upper bound. We also compare our proposed method with the
corresponding constant switching delay-based algorithm and demonstrate that our suggestion of taking into account the different
hardware delays while switching to different frequency bands is essential for scheduling in CRNs.,2013-10-07 12:36:59,下载50次
