Title: Apparatus and method for evaluating variance for iterative interference cancellation
Inventor: JUNG BO HYEON
IPC: H04B1/74
Filed: 2000-12-12
Abstract: PURPOSE: A variance measuring apparatus and method for canceling an iterative interference is provided to measure a noise variance after exactly estimating channel information in order to cancel an iterative interference. CONSTITUTION: A variance measuring apparatus for canceling an iterative interference includes a MUD(Multi-User Detector)(21), a MAP(22), and an iterative interference canceller(23). The MUD(21) calculates an LLR(Log Likelihood Ratio) defined using the output value(yi¬(k)) of a multi-user's matched filter and Ii¬(k)(m-1) defined as the (m-1)th LLR transmitted by interference users and detects a channel estimation likelihood value(LLRinput(xi¬(k);m)). The MAP(22) executes iterative decoding using the channel estimation likelihood value(LLRinput(xi¬(k);m)) detected through the MUD(21). The iterative interference canceller(23) determines a decoding bit(hard decided value) after canceling an interference through the final decoding using the LLR value calculated through the MAP(22) and LLRinput(xi¬(k);m-1), regresses LLRioutput(xi¬(k);m-1), a soft decided value, to the priori values of the MAC input value, estimates channel information iteratively generated every decoding, and measures a noise variance.
