[0030] System and method overview
[0031] Such as figure 1 As shown, embodiments of the present invention provide a method and system for wireless communication between a transmitter 100 and a receiver 150 via an uncorrelated MIMO dual-selective channel subject to time-varying fading and multipath delay. Time-varying fading causes inter-carrier interference (ICI), while multipath delay causes inter-symbol interference (ISI). The system is capable of sending high-speed data even for situations where the transceiver is moving at extreme speeds, such as mobile phones carried in high-speed trains and airplanes.
[0032] An encoder 110 in transmitter 100 encodes 110 a sequence of data symbols 101 using an error correction code (ECC) 115 to produce encoded data symbols 111 . The encoder may use a capacity-approaching forward error correction (FEC) code, such as a low density parity check (LDPC) code, a turbo code, a repetition accumulation code, or other similar codes.
