1. A communication system for coding and communicating data frames for high bandwidth communication over a Controller Area Network (CAN) communication bus, each data frame has a logical structure according to CAN Standard ISO 11898-1 and is composed of a sequence of bits and waveform defining a Start-Of-Frame-Bit, an Arbitration Field, a Control Field, a Data Field, a CRC Field, an Acknowledge Field and an End-Of-Frame Field, the communication system comprises at least one transmitting node and at least one receiving node, and a controller unit of the transmitting node is to code and transmit the Data Field by modulating a sequence of pulses with varying durations defined by deviating a number of level transitions of a known cyclic signal waveform by a series of delays, wherein the series of delays is indicative of a sequence of data symbols to be transmitted and wherein the series of delays is calculated by applying different modulation calculations for odd and even elements.
