Systems and methods for multiple-input multiple-output communications systems

At least one computer-readable medium including program instructions which, when executed by at least one processor, cause the at least one processor to perform a method for error correction in a multiple input multiple output (MIMO) wireless communication system, the method comprising:

• receiving an original signal in an initial MIMO format;
• detecting an error in the original signal;
• notifying a transmitter of the error detected in the original signal;
• receiving a new retransmitted signal in a first retransmitted MIMO format, different from the initial MIMO format, the new retransmitted signal including at least a fraction of encoded bits of the original signal;
• correcting the original signal by applying the new retransmitted signal to the original signal;
• sending feedback about the original signal to the transmitter,
• wherein the transmitter switches to the first retransmitted MIMO format from the original MIMO format according to the sent feedback,
• wherein the original MIMO format and the first retransmitted, MIMO format are chosen from the group including:
• closed-loop MIMO, open-loop MIMO, multi-user MIMO, single-user MIMO, non-cooperative MIMO, cooperative MIMO, non-CDD MIMO, or CDD MIMO, and
• wherein the initial MIMO format and the first retransmitted MIMO format have a different MIMO rate.
