MIMO OFDM Simulator:
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: ：该文研究OFDM 系统在总功率和误比特率限定下最大化传输速率的问题，并且考虑实际系统中整数比特的限制，
提出基于灌水法则的两种比特分配算法——改进贪婪算法和对分灌水线搜索法-The maximization of data rate under the constraint of total transmit power and bit error rate is a
considerable issue in OFDM system. Recognizing that the number of bits on each subcarrier must be a discrete
number for real systems, this paper proposed two bit allocation algorithm which are modified greedy algorithm
and water filling level binary searching algorithm. Platform: |
