OFDM.m: OFDM Simulator (outer function)
create_channel.m: Generates a Rayleigh fading frequency-selective channel, parametrized by the antenna configuration, the OFDM configuration, and the power-delay profile.
svd_decompose_channel.m: Since full channel knowledge is assumed, transmission is across parallel singular value modes. This function decomposes the channel into these modes.
BitLoad.m: Apply the bit-loading algorithm to achieve the desired bit and energy allocation for the current channel instance.
ComputeSNR.m: Given the subcarrier gains, this simple function generates the SNR values of each channel (each singular value on each tone is a separate channel).
chow_algo.m: Apply Chow s algorithm to generate a particular bit and energy allocation.
EnergyTableInit.m: Given the SNR values, form a table of energy increments for Platform: |

Description: This function calculates the ergodic and outage capacity of a MIMO Rayleigh
channel considering no CSIT (equal power allocation) and perfect CSIT
(waterfilling power allocation). In both cases perfect CSIR is assumed. The
channel is assumed to be spatially correlated according to a Kronecker
model but temporally uncorrelated.- This function calculates the ergodic and outage capacity of a MIMO Rayleigh
channel considering no CSIT (equal power allocation) and perfect CSIT
(waterfilling power allocation). In both cases perfect CSIR is assumed. The

Description: In this paper, we present a Selected Mapping (SLM) PAPR reduction technique for MIMOOFDM
system with special protection of Side Information (SI). Selected Mapping (SLM)
is a powerful PAPR reduction technique since it does not cause any signal distortion and
simple to implement. As a special protection for the Side Information (SI) of SLM technique,
we propose a SI power allocation procedure. Simulation results show that our proposed
technique gives significantly better BER performance than the ordinary SLM technique for
MIMO-OFDM systems. Analysis for the optimum SI power allocation is also presented. Platform: |
