This discussion will be primarily focused on the problem of jointly suppressing the different interferences such as
Multiple Access Interference (MAI) and Intersymbol Interference (ISI), which are the limiting sources of
interference for high data-rate wireless applications, as in wireless multimedia or Spread Spectrum Code Division
Multiple Access. After describing the general problem of interference rejection in wireless communications, we
present a signal subspace approach to blind joint suppression of MAI and ISI. Then, follows a discussion of a
powerful iterative technique for joint interference suppression and decoding called Turbo multiuser detection that
is especially useful for wireless multimedia packet communications. We also discuss space-time processing
methods that employ multiple antennas for interference rejection and signal enhancement. These are not all the
available methods, but the ones that we consider available to us in the near future. We will deal on; a) Co-Channel
interference mitigation detectors, b) Partially suppression of MAI and ISI, c) MAI near–far resistance
architecture, and d) Successive interference algorithms.
