Bit Rate Optimization with MMSE Detector for Multicast LP-OFDM Systems

Algorithm 2

Bit-loading algorithm for multirate multicast systems.

𝑇_𝑊; ∀𝑘,𝑅_𝑘(0)=1

for all user 𝑘∈[1;𝐾]  do

 Compute {𝑟_𝑘,𝑛}_{𝑛∈[1,𝑁]} using ZF or MMSE detection bit-loading

end for

for all time slot index 𝑖∈[1;𝑇_𝑊]  do

 Select the user index 𝑘^∗ as defined in (30)

 Compute {𝑟_𝑛(𝑖𝑇)}_{𝑛∈[1,𝑁]} using (29)

 Compute 𝑅_𝑘(𝑖𝑇) using (24)
