In accordance with a first aspect, a method, apparatus and system is disclosed for communicating within a TDMA communication system comprising receiving data from a plurality of transmitters in a stream of TDMA super-frames, wherein each transmitter transmits payload data in one particular frame within a defined super-frame, each super-frame comprising M frames, where M is a positive integer greater than one, determining, using a processor, a quality of received data from said transmitters, and if the quality of received data from one of said transmitters is below a quality threshold, granting said one of said transmitters the right to transmit data within a second frame in said super-frames, and collectively processing in a processor said data in both frames of said super-frame assigned to said one of said transmitters to reconstruct said data from said one of said transmitters Also, a method, apparatus and system for processing data received in a TDMA communication system utilizing a stream of TDMA super-frames, each super-frame having a structure comprising M frames, each frame designed to carry data of a duration of Y time units, from a different communication channel, where Y is a positive integer, said method comprising dividing said super-frame into N/M hyper-frames, where N is a factor of M, and partitioning said data from each of said transmitters into mini-frames of duration Y/N and interleaving said mini-frames of data from each of said transmitters into a TDMA transport stream comprising super-frames of M*N mini-frame.

TDMA voice communication method and apparatus

Systems () and methods for providing TDMA communication. The methods involve determining a channel quality of an uplink channel. A communication delay is set equal to an integer value 'K'. 'K' is selected based on the channel quality. &#x201c;K&#x201d;&#x2266;&#x201c;N&#x201d;. &#x201c;N&#x201d; is a total number of frames of a time slot of a TDMA signal (). Thereafter, First Message Data (FMD) is communicated over the uplink channel in a first time slot (A) of an uplink signal (). An Error Control Process (ECP) is performed using FMD to at least identify First Error Free Message Data (FEFMD). Filler data and/or at least a portion of FEFMD is communicated over a downlink channel in a last &#x201c;N&#x2212;K&#x201d; frames of a time slot (A) of a downlink signal (), when &#x201c;K&#x201d;&#x3c;&#x201c;N&#x201d;.

Systems and methods for time division multiple access communication with automatic repeat request error control

A method and apparatus for communicating wirelessly comprising creating a plurality of sub-carrier signals by quadrature amplitude modulating data onto a plurality of sub-carrier frequencies spaced apart by a sub-carrier frequency spacing interval, frequency shifting the sub-carrier signals by one half of the sub-carrier frequency spacing interval, and modulating the sub-carrier signals onto a radio frequency carrier wave for wireless transmission.
