%%%%%----------- 2022/08/05 readme.txt -----------%%%%% This .txt document describes how to make use of the data in this depository. It is to be used alongside journal article Concurrent Multiband Direct RF Sampling Receivers, accepted for publication in IEEE Transactions on Wireless Communications 2022/07/20. %%%%%------------- MATLAB Code ----------------%%%%% Two key .m files are contained in this depository. MultibandReceiverAnalysis.m is used to calculate SNRs for a given set of input powers to a multiband receiver, the parameters of which are also defined inside the file. It also estimates the EVM for each input power, as shown in Fig. 5 The second key file is BBModel.m inside BasebandSimCodeAndData.zip. This uses the SNRs generated by MultibandReceiverAnalysis.m to simulate the LTE baseband BLER for a given receiver situation and set of input powers. The other three .m files in the .zip folder are called by BBModel.m and do not run independently. The .mat files in the .zip folder are example input data, which were used to generate Fig. 6. The naming format is: Band%n%%samp%%K%.mat where %n%=[1:4] is the band of interest; %samp%=[Nyq Sub] is whether Nyquist (10GSample/s) or Subsampling (250MSample/s) sampling has been used; %K%=[Multi Single] is whether the receiver is in Multiband or Singleband operation. %%%%%------------- System Measurements ----------------%%%%% Measured data for the cabled experiment (EVM and BLER for a given receive power and system setup, as shown in Figs. 8-10) is contained in MeasurementsCabled.mat and consist of real vectors. Received powers are in dBm, EVM is in % and BLER is unitless. Some vector values are NaN in order to maintain equivalent lengths between comparable values for plotting purposes. The naming convention is: %meas%%s%%K%%n% where %meas%=[rxPow evm bler] is the measurement type; %s%=[N S] is the sampling used (Nyquist or Subband); %K%=[M S] is the receiver scenario (Multiband or Singleband); and %n%=[1:4] is the band of interest being measured. Measured OTA data from inside the anechoic chamber is contained in OTAChamberData.mat and from measurements in an office environment in OTAOfficeData.mat (Fig. 12). The data is in the same format as MeasurementsCabled.mat. %%%%%------------- Document Ends ----------------%%%%%
