Abstract:
1. A method of transmitting and receiving at least one frame of data ([D]) over a communications link, said frame of data comprising a matrix of up to N 2 data elements, N being greater than 1, said method comprising: obtaining an orthonormal matrix set, said orthonormal matrix set comprising a first N×N matrix ([U wherein said communications link and said orthonormal matrix set are chosen to be capable of transmitting at least N elements from a matrix product of said first N×N matrix ([U said time spreading interval consisting of at least N time slices; forming a first matrix product of said first N×N matrix (pa and said frame of data ([D]); permuting said first matrix product by an invertible permutation operation P forming a permuted first matrix product P([U forming a second matrix product of said permuted first matrix product P([U transmitting, using a hybrid analog and digital transmitter, and receiving, using a hybrid analog and digital wireless receiver, said convoluted data matrix over said communications link by the steps of: 1: for each single time-spreading interval, selecting N different elements of said convoluted data matrix; 2: over different said time slices in said time spreading interval, using said transmitter to perform the process of selecting said N different elements of said convoluted data matrix, modulating said N different elements, and transmitting said N different elements so that each said N different elements are transmitted over said time spreading interval; 3: using said receiver to perform the process of receiving said N different elements of said convoluted data matrix over different said time slices in said time spreading interval; 4: demodulating said N different elements of said convoluted data matrix; repeating steps 1, 2, 3, and 4 up to total of N times, thereby reassembling a replica of said convoluted data matrix at said receiver; using said receiver, said first N×N matrix ([U wherein an arbitrary data element of an arbitrary frame of data ([D]) cannot be guaranteed to be reconstructed with full accuracy until a substantially complete replica of said convoluted data matrix has been recovered.
