An ICOM IC-7300 Radio Tuned to the 20 Meter Band. The ICOM IC-7300 is a multimode 6 meter, 4 meter (ITU Region 1 only) and HF base station amateur radio transceiver. [1] The IC-7300 was announced to the public at the Japan Ham Fair in 2015. [2] The radio has 100 watts output on CW, SSB, and FM modulations and 25 watts of output in AM. [3]
The highest absolute cross-correlation in this set of codes is 2 (n+2)/2 + 1 for even n and 2 (n+1)/2 + 1 for odd n. The exclusive or of two different Gold codes from the same set is another Gold code in some phase. Within a set of Gold codes about half of the codes are balanced – the number of ones and zeros differs by only one. [5]

A low code-rate close to zero implies a strong code that uses many redundant bits to achieve a good performance, while a large code-rate close to 1 implies a weak code. The redundant bits that protect the information have to be transferred using the same communication resources that they are trying to protect.
The Icom IC-V82 is a VHF handheld transceiver with coverage in the two-meter band (144–146 MHz) and a maximum output power of 7 watts. [8] It was manufactured and sold by Icom from 2004 to 2014. [9] [10] [11] Following its discontinuation, Icom issued an advisory warning about counterfeit radios, including the IC-V82.

It is still notably used today for satellite communications, such as the DVB-S digital television broadcast standard. [9] In a looser sense, any (serial) combination of two or more codes may be referred to as a concatenated code. For example, within the DVB-S2 standard, a highly efficient LDPC code is combined with an algebraic outer code in ...
