function rx_signal = channel(tx_signal cir sim_options);
global sim_consts;
% 选择天线数量
[n_tx_antennas n_rx_antennas] = get_n_antennas(sim_options);
% Channel effect
rx_signal = zeros(n_rx_antennas size(tx_signal2)+size(cir2)-1);
% 所定义的列数为卷积长度
for rx_ant = 1:n_rx_antennas
for tx_ant = 1:n_tx_antennas
rx_signal(rx_ant:) = rx_signal(rx_ant:) + ...
conv(tx_signal(tx_ant:) cir((rx_ant-1)*n_tx_antennas+tx_ant:));

% Add noise
% calculate noise variance
% 64/52 scale factor normalizes the noise with the used subcarrier number
noise_var = 64/52/(10^(sim_options.SNR/10))/2;
noise = sqrt(noise_var) * (randn(n_rx_antennas len) + j*randn(n_rx_antennas len)); % 归一化噪声
extra_noise = sqrt(noise_var) * (randn(n_rx_antennassim_consts.ExtraNoiseSamples) + ...
j*randn(n_rx_antennas sim_consts.ExtraNoiseSamples));
% end noise is added to prevent simulation from crashing from incorrect timing in receiver
end_noise = sqrt(noise_var) * (randn(n_rx_antennas170) + j*randn(n_rx_antennas 170));
% add noise
rx_signal = rx_signal+noise;
% extra noise samples are inserted before the packet to test the packet search algorithm
rx_signal = [extra_noise rx_signal end_noise];
%Create frequency offset
rx_signal = create_freq_offset(rx_signal sim_options.FreqError);
