function BER1m = mrc_new(M, frmLen, numPackets, EbNo)

% mrc_new: Maximal-Ratio Combining for 1xM antenna configurations.

% ber_mrc = mrc_new(M, frmLen, numPackets, EbNo) computes the bit-error rate

% estimates via simulation for a Maximal-Ratio Combined configuration using

% one transmit antenna and M receive antennas, where the frame length, number

% of packets simulated and the Eb/No range of values are given by M, frmLen,

% numPackets, EbNo parameters respectively.

% The simulation uses BPSK modulated symbols with appropriate receiver

% combining.

% Suggested parameter values:

% M = 1 to 4; frmLen = 100; numPackets = 1000; EbNo = 0:2:20;

% Create BPSK mod-demod objects

P = 2; % modulation order

bpskmod = modem.pskmod('M', P, 'SymbolOrder', 'Gray', 'InputType', 'Integer');

bpskdemod = modem.pskdemod(bpskmod);

% Pre-allocate variables for speed

z = zeros(frmLen, M);

error1m = zeros(1, numPackets); BER1m = zeros(1, length(EbNo));

% Loop over EbNo points

for idx = 1:length(EbNo)

% Loop over the number of packets

for packetIdx = 1:numPackets

data = randi([0 P-1], frmLen, 1); % data vector per user/channel

tx = modulate(bpskmod, data); % BPSK modulation

% Repeat for all Rx antennas

tx_M = tx(:, ones(1,M));

% Create the Rayleigh channel response matrix

H = (randn(frmLen, M) + 1i*randn(frmLen, M))/sqrt(2);

% Received signal for each Rx antenna

r = awgn(H.*tx_M, EbNo(idx));

% Combiner - assume channel response known at Rx

for i = 1:M

z(:, i) = r(:, i).* conj(H(:, i));

end

% ML Detector (minimum Euclidean distance)

demod1m = demodulate(bpskdemod, sum(z, 2)); % MR combined

% Determine bit errors

error1m(packetIdx) = biterr(demod1m, data);

end % end of FOR loop for numPackets

% Calculate BER for current idx

BER1m(idx) = sum(error1m)/(numPackets*frmLen);

end % end of for loop for EbNo
