Patent ID: 6975585

Claim:
A method of communicating information within a local area network using a master station forming a residential gateway for transmitting and receiving information from a broad band network and distributing said information in the local area network to a number of slave transmitter/receivers comprising the steps of a. dividing said information into mapping frames; b. applying said mapping frames to a plurality of channels; said channels each allocated a complex transmit symbol c. transmitting a signal characterized by the empirical relationship: x ⁡ ( 4 ⁢ mK + n ) = ∑ k = 0 K - 1 ⁢ ⁢ A k m · ⅇ - j ⁢ ⁢ nk ⁢ π K + ∑ k = 0 K - 1 ⁢ ⁢ ( A K - k m ) * · ⅇ - j ⁢ ⁢ n ⁡ ( K + k ) ⁢ π K where A k m is the k-th symbol of the m-th mapping frame, where x( ) is a discrete-time transmit signal, n is an index from 0 to 4K, (A m K−k )* is a complex conjugate of a value of the (K−k)th symbol of the m-th mapping frame, k is a channel index, and K is a maximum number of symbols per mapping frame.
