y[k, l] = ∑ki=-kv to kv∑l=0 to li = b[ki , li ] h[ki , li ] x[[k − ki ]N , [l − li ]M] =

h[k, l] ∗ x[k, l] (2D Circular Convolution)

h[ki , li ]= e−j2π ki/ NT *li/ MΔf . and [·]N , [·]M denote modulo N and M operations, respectively. We have the total number of paths: ∑ki kv=−kν to kv ∑ li =0 to li b[ki , li ] = P. Each path circularly shifts the transmitted symbols by the delay and Doppler taps

for k=0 to 32 , l=0 to 32 , ki =5 li =10

, b[ki , li ] ∈ {0, 1} is the path indicator, i.e., b[ki , li ] = 1 indicates that there is a path with Doppler tap ki and delay tap l i with corresponding path magnitude hˆ[ki , li ], otherwise, there is no such path, i.e., b[ki , li ] = 0 and hˆ[ki , li ] = 0

how can I represent y[k,l] in MATLAB
