A method for constructing orthogonal codes of length N for use in a network utilizing quasi-synchronous code division multiple access combined with time division duplexing. The method determines the balanced vectors of length N, being all possible cross-correlation vectors resulting from zero cross-correlation of codes of length N. An arbitrary code of length N is utilized, and a bitwise XOR-ing is performed with all the balanced vectors to produce a set of codes with which the arbitrary code is orthogonal. A bitwise XOR-ing of the original balanced vectors is performed and the code is added to a set of orthogonal codes if the result of the bitwise XOR-ing of the original balanced vectors is balanced. The method is repeated until the set of orthogonal codes is complete.

A hardware and software co-design environment and design methodology based on a data-model that allows one to specify, simulate, and synthesize heterogeneous hardware and software architectures from a heterogeneous specification. The environment and methodology of the invention allow for the interactive synthesis of hardware and software interfaces. The environment defines primitive objects to represent a specification of an essentially digital system. The primitive objects are defined by describing the specification of the system in one or more processes, each process representing a functional aspect of the system. Further, each of the processes have ports which are connected to ports of other processes with a channel. The ports structure communication between the processes.
