Abstract
System () and methods () for receive processing of a burst communication system where co-channel signals () collide in a receiver (). The methods comprise: simultaneously receiving co-channel signals () transmitted from remote transmitters (-) at a first frequency; and independently performing a first iteration of a Turbo MUD process for a first co-channel signal and a second co-channel signal. The Turbo MUD process comprises: segmenting each of the first and second co-channel signals into a plurality of segments () each having a unique SINR; computing a noise plus interference variance estimate for each segment; computing first bit likelihood values for each segment based on the noise variance estimate; computing second bit likelihood values for each segment based on the first bit likelihood values; and using the second bit likelihood values (i.e., soft in soft-out) to generate a first estimate of the first and second co-channel signals.
