Description: This project demonstrates OFDM with adaptive modulation applied to Multiple-Input Multiple-
Output (MIMO) systems.
The analysis and simulation
is considered in two stages. The rst stage involves the application of a variable-rate
variable-power MQAM technique for a Single-Input Single-Output (SISO) OFDM system.
The second stage applies adaptive modulation to a general MIMO system
by making use of the Singular Value Decomposition to separate the MIMO channel into parallel
subchannels. Platform: |

There are*three* versions of the 802.11a physical layer model:
R13/IEEE80211a.mdl:
Requires R13 (MATLAB ) and Stateflow (for adaptive modulation control)
R13/IEEE80211a_NoSF.mdl:
Requires R13 (MATLAB), but does not require Stateflow.
R13SP1/IEEE80211a.mdl
Requires R13SP1 (MATLAB), but does not require Stateflow.
This latest version also includes some bug fixes.
All Simulink models require the Communications Blockset. Platform: |

Description: Abstract—In this paper we present an initial performance
evaluation of the 3GPP UTRA Long Term Evolution (UTRA
LTE) uplink with baseline settings. The performance results
are obtained from a detailed UTRA LTE uplink link level
simulator supporting OFDMA and SC-FDMA schemes. The basic
transmission scheme for uplink direction is based on singlecarrier
transmission in the form of DFT Spread OFDM with
an MMSE receiver. Two antenna configurations, SISO and 1x2
SIMO are considered in the analysis of spectral efficiency in
addition to Adaptive Modulation and Coding (AMC) and L1-
HARQ. For assessment purposes, the performance results of
SC-FDMA are compared with OFDMA. It is shown that 1x2
SIMO greatly increases the spectral efficiency of SC-FDMA
making it comparable to OFDMA, especially for high coding
rate. Furthermore, SC-FDMA has a flexibility to increase BLER
performance by exploiting frequency diversity. Platform: |

Description: Modulation is the approach by which a carrier wave has the ability to convey the message or digital signal. There are three essential methods to this: amplitude, frequency and phase shift keying. More bits per symbol or period can be encoded using a high order of modulation. Distinctive order modulation permits to send more bits per symbol and in this way attain higher throughputs or better spectral efficiencies [5]. The utilization of adaptive modulation (AM) permits a wireless system to pick the highest order modulation upon the channel conditions. Platform: |
